The BookDumb Bob just turned in his essay. It wasn't just regular bad; it was the ''Film/Plan9FromOuterSpace'' of high school essays. It was [[EpicFail so bad]] that it somehow broke literature. Obviously, the regular grading scale is not ''extreme'' enough for Bob's horrifying essay, so Bob's teacher pegs his work with a grade completely off the scale: an F[=-=][=-=].

In the United States and some of Western Europe, an F is the lowest grade possible. There are no additions to it, not a plus or minus. F simply means failure, no matter how bad. However, this is not always the case in the world of fiction. Sometimes, the only way to really show how badly the student performed is to add something special to the F and let the rest take care of itself. This also means that the trope name indicates a performance so bad, that ''[[UpToEleven not even the nonexistent grade of F-]]'' is bad enough for it.

This trope is for negative grades that go off the scale, from a simple F- all the way down to Z-. Or if grades are percentage-based, the percentage will be negative, meaning that the character got more answers wrong than actually existed. A staple of school comedies that don't take themselves particularly seriously. An inversion of RankInflation. Contrast TheBGrade. When it's a reviewer doing this, it's BrokeTheRatingScale.



[[folder:Audio Plays]]
* InUniverse in ''AudioPlay/BigFinishDoctorWho''. In "Omega," we learn how the eponymous Time Lord got his nickname. Rather than answering the questions on his exam, he took the opportunity to discuss a theory devised by a "[[FantasticRacism lesser race]]." His instructor at the Prydonian Academy decides to give him an "omega" grade, a grade so bad it was previously only ''theoretical''.

[[folder:Comic Strips]]
* ''ComicStrip/{{Peanuts}}'':
** In one strip, Sally shows her school report to Charlie Brown and asks him what grade he thinks it'll get. His response: "Do they give out Zs?" It appears that "Z" grades do exist in the world of ''Peanuts'' since Peppermint Patty once expressed that she has a straight-Z average in school.
** There is also a strip where Patty runs up to Marcie, crowing, "I got an 'N' on my English test! That's the highest grade I've ever gotten!", only for Marcie to tell her she's holding the paper sideways.
** Another time Patty gets a Z minus and complains to her teacher, who raises it to a Z.
** In ''Snoopy! The Musical'', Lucy was given a Z by her teacher which she refutes as sarcasm.
* In one ''Squirt'' strip, Squirt's homework was so bad that his teacher extended the alphabet 15 letters past Z in order to aware him an accurate grade.
* From German comic ''Haiopeis'':
-->'''Fish university clerk:''' You got 2 of 2158 points in your last entry test.\\
'''[[TheDitz Shark]]:''' Great, that's the highest I've ever gotten! When can I start to [[MalaProper stupidy]]?\\
'''Fish clerk:''' Why study? That was our entry test for the cleaning staff.
* ''ComicStrip/CalvinAndHobbes'':
** In one comic, Susie is happy with the smiley face sticker she got on her test. Calvin, however, is less than thrilled. When she asks what he got, he refused to tell her, leading her to accuse him of getting a frowny face sticker. Calvin promptly denies it, then comments to himself that he never knew they even ''made'' barfing face stickers.
** In the bug collection assignment arc, Calvin is trying to do the aforementioned project on the day it's due. He gets 4 bugs (out of the 50 he needs; also, one of them is actually a ball of lint) before he has to go to class. Susie snarks that if he labels them scientifically in the next 30 seconds, he might get an F-Plus. At the end of the arc, Calvin tells Hobbes that he got an D-Minus-Minus on the assignment.
* There's a [[http://www.gocomics.com/fminus?ref=comics comic strip]] by Tony Carillo named ''F Minus''. Carillo has said that he sometimes wishes he'd picked a different title, since it means that people who send him [[{{Hatedom}} hate mail]] all tend to make [[NeverHeardThatOneBefore a predictable comment]]...

[[folder:Films -- Live-Action]]
* Happens to the title character in ''Film/BillyMadison'' when he answers a question about the Industrial Revolution as represented in literature with a rambling, incoherent {{Metaphorgotten}} about the title character in ''The Puppy Who Lost His Way'', a book his first grade teacher read to the class. Although the audience cheers and applauds, the principal grades him thusly:
-->'''Principal:''' Mr. Madison, what you have just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

* There is a joke about a student complaining to his university lecturer about his grade.
-->'''Student:''' I don't think this paper deserves an F.\\
'''Lecturer:''' Neither do I, but it is the lowest grade the university will allow me to award.

* In ''Literature/CaptainUnderpants and the Wrath of the Wicked Wedgie Woman'', Ms. Ribble tells George and Harold she's lowering their grades to Fs and Gs.
-->'''George:''' Oh, ''NO''! Not Fs and Gs! ...Hey, what's a G?\\
'''Ms. Ribble:''' It's the only grade lower than an F!\\
'''Harold:''' There's no such grade as a G.\\
'''Ms. Ribble:''' There is now, bub!
* ''Literature/HarryPotter'': Students taking their [=OWLs=] can receive grades of O, E, A, P, D, and T ([[TheSmartGuy Outstanding]], [[SmarterThanYouLook Exceeds Expectations]], [[SoOkayItsAverage Acceptable]], [[BookDumb Poor]], [[TheFool Dreadful]], and [[WhatAnIdiot Troll]]). When Harry first hears of the T grade, he thinks [[ThoseTwoGuys Fred and/or George]] might be pulling his leg (i.e., [[{{Pun}} trolling]] him), but there it is listed among the others on the form. Even Hermione, who normally seems to know all about such things, seems initially surprised by the existence of this grade.
* In ''Literature/RedDwarf: Infinity Welcomes Careful Drivers'', Rimmer usually gets F for Fail on the officer exam, but on two occasions he got X for Unclassifiable; the first time he just collapsed from amphetamine usage, but the second time sheer panic led to him denying his own existence so he wrote "I am a fish" five hundred times. The exam we see involves him leaving an inky handprint on the paper and then fainting, but no-one ever gets a chance to grade it.
* At the end of the picture book ''Bronto Eats Meat'', by Peter Maloney and Felicia Zekauskas, the protagonist of the story writes a school report about Bronto and is given an F- because his report is said to be unrealistic.
* In ''Discworld/InterestingTimes'', one of the faculty members mentions that Rincewind is so inept at magic he once achieved ''negative marks'' in Basic Firestarting. When Rincewind dies, the average spellcasting ability of the entire human race will increase.
* A bully in ''Literature/ToughMagic'' tries to insult the main character by suggesting that he got ''double'' 'F's.

[[folder:Live-Action TV]]
* Jeff and Pierce's [[Recap/CommunityS1E02Spanish101 acted-out Spanish presentation]] on ''Series/{{Community}}'' earns a grade of F (Pierce) and F- (Jeff).
** Zack Perlman, a rich slacker they're trying to recruit in [[Recap/CommunityS4E07EconomicsOfMarineBiology "Economics of Marine Biology"]], has an SAT score of 0. The lowest possible SAT score is 200 (for some reason), and even that is only possible by getting every single question wrong on a multiple choice test.
** While it's possible to get 200 points minimum, the first section of the SAT will deduct 200 points [[WhatAnIdiot if you get all 800 questions wrong]]. Alternatively, [[EpicFail he didn't even sign his name on the paper, let alone attempt it.]]
* On ''Series/SmartGuy'', TJ tutors a basketball player. After taking the test, the student claims he got a G, which he says is worse than an F, but it turns out it was actually a C-. The exact same thing happens on ''Series/SisterSister'', the series about TJ's actors' older twin sisters.
* In one episode of ''Series/ThatsSoRaven'', Eddie raps at a bully, "''Your grades are so low, you get straight Zs!''"
* In the series finale of ''Series/EverybodyHatesChris'', Chris gets a grade Q on his test.
-->'''Chris''': Q? What's a Q?
* ''Series/BoyMeetsWorld'''s Mr. Feeny once threatened to give a student a G for turning in a paper late.
* In one episode of ''Series/SavedByTheBell'', Kelly gets an F from a teacher and asks him if she really deserved that. His response is "No, but they don't allow us to give you an N."
* In ''Series/LeaveItToBeaver'', Lumpy is surprised to be told he has an F after he has been schmoozing with the teacher's daughter in an effort to gain favor.
-->'''Lumpy:''' An F, sir?\\
'''Teacher:''' An F. It's the lowest they allow me to give.
* ''Series/ADifferentWorld'': When Dwayne and Whitley begin dating, Dwayne's grades slip and he gets a C on an assignment. When he complains about this to Ron, his response is, "If you're making C's, Whitley has got to be making Q's!"
* Subverted in an episode of ''Series/GrowingPains'' when Mike is telling his parents what grade he got on a test. He begins with "I..." and Ben blurts out, "An 'I'?! That's worse than an F!" (it turns out it was a more typical grade (a C or a D).)
* In ''Series/GoodTimes'', J.J. is telling a friend that his late father once offered him a reward if he could bring his grade average UP to an F. He then quipped that his report card had contained two M's and a K minus.
* ''Series/BrooklynNineNine'' features a variation, in which it's not so much the grade that's unusual but the 'subject' being failed; Detective Amy Santiago once bitterly notes that the only F grade she ever received was because she somehow managed to fail ''recess''. This also overlaps with TheBGrade, in that Amy was normally an over-achieving TeachersPet, which may go some way towards explaining the F grade:
-->'''Amy:''' ''[bitter mimickry]'' Teachers need a break ''too'', Amy!
* ''Series/{{QI}}'': In the "Nonsense" episode, Sandi Toksvig mentions how her school had three grades for swimming: A, B, and C. She was an F.

* In the Music/TenaciousD skit, "Friendship Test", Jack Black tells Kyle that he passed the titular test only barely, granting him the grade of F+.
* ''Music/WeirdAlYankovic'':
** In "Genius in France", the singer claims to have gotten a negative SAT score.
** In "I Lost on Jeopardy", Don Pardo taunts Al that he is such a complete loser that he doesn't even get "a lousy copy of our home game," the traditional consolation prize for losing contestants on ''Series/{{Jeopardy}}'', and that he has brought shame and humiliation on his family name for generations to come.

[[folder:Puppet Shows]]
* The ''Series/{{Dinosaurs}}'' episode "Network Genius" featured a variation on this trope. Earl was put in charge of deciding which shows a network would show. His choices made the population so dumb that [[TheSmartGuy his son Robbie]] once brought home a report card with several Fs and an M. It turns out that the M grade isn't an indication of how badly Robbie is doing in school, but is actually there because the teacher forgot the alphabet while grading.

[[folder:Theme Parks]]
* The ''Ride/MenInBlackAlienAttack'' ride at Ride/UniversalStudios caps off the ride with Agent J rating your car's score. Do badly enough and he'll give you a G. And that's only because he can't give you an H. [[OverlyLongGag And if he could he'd give you a Q.]]

[[folder:Video Games]]
* In the flash game ''[[http://www.newgrounds.com/portal/view/229014 Stick Avalanche 2]]'', you can get grades of F-, F[=--=] and F[=---=].
* In ''VideoGame/LuigisMansion'', the lowest grade is H (meaning the mansion is replaced with a little tent), although you have to try to do that badly. There are even a few Let's Plays of the game with the [[MinimalistRun goal of finishing with an H.]] The same is true of the first generation of 5-key ''VideoGame/{{Beatmania}}'' games.
* ''VideoGame/CrossEdge'' has [[GameplayGrading battle rank evaluations]] that go in descending order from S, to A, B, C, D, E and F, and [[RankInflation keep going]] to G, H, ''I''...
* In ''VideoGame/ZorkGrandInquisitor'', if you read the grade report on the bulletin board in G.U.E. Tech, you'll see that the titular Grand Inquisitor got a Z- in magic due to his Magic Deficit Disorder.
* In ''ConfidentialMission'', shooting civilians and using continues subtract from your score. As shown in the AttractMode tutorial, it is possible to have a negative score; if achieved, ''your score turns red.''
* Most 3D ''Franchise/SonicTheHedgehog'' games have the "E" rank which is basically saying [[EpicFail you did really horribly]]. It's most evident in ''VideoGame/SonicUnleashed'' where getting an E-rank causes the grade to ''go tumbling off'' and has Sonic falling down and asking to try again. [[http://www.youtube.com/watch?v=yODLkaF8F-Y Even the music knows how epically you failed!]]
* In the flash game ''VideoGame/{{N}}'', your score for each episode of 5 levels is how much [[TimedMission time]] you had left at the end. You start at 90 seconds and can gain more time by collecting gold. The game also records your best individual level scores, which are the times you'd have left at the end of them if you'd started at 90 seconds - and allows you to play back your best runs. So if you have more than 90 seconds to start a level, you can get a negative score for the level. If this happens, your score shows up as "[=---.---=]" and you won't be able to replay yourself completing that level. (You still can for the whole episode.)
* In the ''VideoGame/FalloutNewVegas'' DLC pack ''Old World Blues'', this is what Richie Marcus's (Dr. Borous' High School bully) grades are listed as in the replica high school.
* ''VideoGame/KillingFloor'': Female characters can taunt the zeds with an "F-".
* In ''VideoGame/CrazyTaxi'', finishing with no money gets a "grade" of No License. The next lowest grade is "E".
* Avan Hardins of ''VideoGame/ValkyriaChroniclesII'' is considered an IdiotHero. He once got a -10 on an exam because he got no answers correct and then lost points for penmanship.
* In ''VideoGame/WorldOfFinalFantasy,'' Tama discovers an easy way to travel back and forth between the world of the Lilikins and the Jiants (where Lann and Reynn come from), which Lann decides to call the "Super Port-a-Party". Tama hates the name, and gives him an "F" for effort. Lann thinks the name is so bad that it deserves an even lower grade, so she gives him an "H".
* [[AIIsACrapshoot ISIC]] from ''VideoGame/BattleBorn'' will sometimes give his opponent a "combat grade" of "F minus minus minus minus minus minus minus minus minus [[OverlyLongGag minus minus]]" upon scoring a kill.

[[folder:Web Animation]]
* The TropeNamer is the ''WebAnimation/HomestarRunner'' sbemail "for kids", in which Strong Bad assigns the children in his studio audience the eponymous grade.
** He also gets a score of -45/150 on ''VideoGame/PeasantsQuest'' before checking the email.
** In "hygiene", Strong Bad as Gene gets a G-, but this is apparently okay because he's "soooo charming".
* In the Flash animation ''Final Fantasy A+'', adventuring students fight a boss of some sort for their final exams, with grades awarded by how many {{Hitpoints}} they had left at the end (all students have a maximum of 100). By the final boss fight, the hero is down to zero hitpoints, but [[{{Determinator}} keeps going]]. As he continues to take damage his grade drops from "F" to "FF". [[spoiler:Though by the time he finally wins it's revealed that it actually stands for "Final Fighter A+".]]

[[folder:Web Comics]]
* ''Webcomic/TheInexplicableAdventuresOfBob''— in a ShoutOut to ''ComicStrip/{{Peanuts}},'' Jean is seen grading papers, and one by "Patty" has a Z minus. The paper next to it gets a [[UsefulNotes/ProgrammingLanguage C plus plus.]]

[[folder:Web Original]]
* ''WebVideo/AtopTheFourthWall'': In Linkara's review of ''Newmen'' #1, he references an F ''Triple'' Minus.
* ''WebVideo/TVTrash'': Chris's final grade for [[WesternAnimation/FamilyGuy "Family Gay's"]] attempt at a gay rights aesop? Quintuple F-Minus!
* Website/SomethingAwful used to review really bad movies and computer games, giving them ''negative'' 1-10 points in categories like graphics, plot, gameplay, and so forth.

[[folder:Western Animation]]
* In the ''WesternAnimation/DaveTheBarbarian'' episode "Rite of Pillage", Dave receives grades of F and F- on first two tests, Battle Cry and [[HehHehYouSaidX Laying]] [[ToiletHumour Waste]] respectively. After failing his third test, Plundering, his examiner becomes furious at his performance.
-->'''Pillage Master:''' Oh there must be something lower than F-. ''(furiously scribbles "Z" over and over again on Dave's report card)'' Z!!! ''Z!!!'' Z! Z! Z! Z! Z!...
* Parodied as well as TheBGrade in ''WesternAnimation/{{Futurama}}'':
-->'''Wernstrom:''' I give your invention the worst grade imaginable: an A-minus-''minus''!
* ''WesternAnimation/TheFairlyOddParents'': Timmy Turner has a history of getting these, while Crocker gives F as one of his catchphrases. In fact, Crocker is shown to have a super huge "F" stamp reserved especially for Timmy, which he has referred to as "[[{{Superhero}} Super]] F" more than once.
-->'''Timmy:''' ''[[[ItMakesSenseInContext sinking into his pile of failing grades]]]'' [[BigNo Nooooooooooo!]] [[MoodWhiplash Cool, there's a D in here!]]
* ''WesternAnimation/{{Doug}}'': In the episode "Doug's Bum Rap", Doug imagines himself getting the lowest score of -60 on his English test, earning him a spot on the infamous Hall of Losers as the "Stupidest Boy in the World".
* ''WesternAnimation/{{Arthur}}'':
** In one episode, Buster worried about getting an "F" on an assignment he did wrong and Arthur quipped that he could even get a "G" or an "H."
** The episode "Team Trouble" inverts this a bit. Arthur, Buster, and Francine, upon realizing their group assignment on Ancient Rome has several kinks to work out, all have an ImagineSpot: Arthur imagines an F, Buster imagines multiple Fs, and Francine imagines an F+. Which is a BrickJoke from earlier in the episode, when Arthur and Buster imagined getting A's, and Francine an A+.
* In the ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'':
** In the episode "Sheen's Brain", Sheen gets [[UpToEleven FOUR]] minuses on a test. One of the things he wrote down was that Ultra Lord (a [[ShowWithinAShow fictional]] superhero that Sheen is fanatically obsessed with) [[ArtisticLicenseHistory was the first president of the United States]].
--->'''Jimmy and Carl:''' ''Quadruple'' F MINUS?!\\
'''Sheen:''' How was I supposed to know that Ultra Lord wasn't the father of our country? That's what it says on the Ultra Lord website!\\
'''Jimmy:''' Wait, didn't ''you'' write the Ultra Lord website?\\
'''Sheen:''' Your point? ''[[[{{Beat}} Jimmy stares at him blankly]]]'' Oh.
** Inverted in one episode where Jimmy received an "A++".
* ''WesternAnimation/TheEmperorsNewSchool'' episode "Kuzclone" has the eponymous clone flunk Kuzco's tests so badly he gets a G-.
* ''WesternAnimation/ThePowerpuffGirls'': When Mojo Jojo starts teaching a linguistics class, he hears everyone and tells everyone that based on what he's already heard he would give them an F, then he goes on a rant where he says he would give them all a Z if the scale went down that low (he also asks why they skip E).
%%* Discussed in ''WesternAnimation/TheWeekenders''.
* ''WesternAnimation/{{Beetlejuice}}'': Beetlejuice gets a G, Q, and Z when he's forced to go back to school.
* Otto of ''WesternAnimation/RocketPower'' gets in trouble with his dad for earning a "check minus minus" in Classroom Citizenship.
* On ''WesternAnimation/TheJetsons'', Elroy gets his report card switched with a student who gets an H.
* In ''WesternAnimation/MovilleMysteries'', the school jock always gets the same grade: X, so awful it can't be graduated. His parents always praise the grade as it was an A because he's such a good athlete that talent hunters always are chasing after him with million-dollar contracts.
* On an episode of ''WesternAnimation/MuppetBabies'' where the characters were pretending to go to school, Piggy ends up giving Gonzo a "W" on his report card. Although it more than likely stood for "weird" and Gonzo was very pleased with his marks.
* In an episode of ''WesternAnimation/CodenameKidsNextDoor'', Numbuh One receives a double F minus for a report. In a later episode, Numbuh Five gets a double F minus for claiming a dog ate her homework (which actually happened), and then warned by the teacher that it is possible to get a '''triple''' F minus in her class.
* In ''WesternAnimation/WhateverHappenedToRobotJones'', most people in the class got an F, some getting an F-, one getting an F'''[[DownplayedTrope +]]''', and the title character--the only passing person in the class--getting a [[TheBGrade C-]], and proceeding to go out of his way to negotiate with the scantron to get a better grade because it was "below average".

* ''WesternAnimation/JohnnyTest'' has the episode "Extra Credit Johnny" where Johnny fails so much that he gets a Z-, and then goes further, getting a ZZ-.
* A very early episode of ''WesternAnimation/SouthPark'' has the boys turning in a report on the Vietnam War based on an incredibly inaccurate depiction given to them by Stan's Uncle Jimbo. Mr. Garrison gives them an F-, and Stan openly wonders if he can do that.
* ''WesternAnimation/{{Gawayn}}'': When Elspeth has to go to magic school to get her diploma, the Duke sabotages her exams; causing her to get an F, then an F minus, then an F minus minus.
* In the Canadian animated series ''WesternAnimation/YvonOfTheYukon'', one episode saw the titular character do so badly in an exam that he gets a G. He's so haunted by it that he becomes determined to get an F...except he starts doing so well in everything that he only gets A grades.
* ''Series/StrangeHillHigh'':
** In "End of Terminator", when NIMROD starts malfunctioning, he gives Tanner a 'G' on his math test. Tanner protests that 'G' isn't even a real grade, but is ignored.

* ''WesternAnimation/{{Fangbone}}'': In "The Duck of Always", Bill has a nightmare where he gets an F minus in 'World Saving'.

[[folder:Real Life]]
* In England and Wales, in addition to the normal set of grades, 'U' (unclassified) at both [=GCSE=] and A-level. This can mean you didn't score highly enough to be offered a certificate. Paul Merton frequently references the U he received in GCSE metalwork in his comedy and TV appearances; in the audio commentary to ''The Very Best of Series/HaveIGotNewsForYou'' from 2002, he tells Ian Hislop that he'd have done better if he hadn't shown up for the exam at all.
** The full system of GCSE grades (before the 2017 revamp using numbered "grades" instead) started with A* at the top, then going from A down to G (or in some cases even H - meaning F was not the worst score possible), which meant scoring at least 20%. Slightly under this was grade N (for Near Miss), followed by U (ungraded - so bad it doesn't even count - and then finally X (for scoring zero). "Passing" was generally defined as scoring at least a grade C. Grades D and below were considered failing grades, while an N, U, or X were just considered epic failure.
** Depending on the subject taken at university, some exams can be multiple choice. In these cases, given the difficulty of university and to discourage students simply attempting to guess the answers, the scoring system awards 1 mark for a correct answer or -1 mark for choosing a '''wrong''' answer (as opposed to simply given 0 marks); thus, if you are unsure about the answer, it is better to pass over the question than to take a wild guess. Following from this, it becomes obvious that if you get more questions wrong than you got right, you will receive a '''negative''' score (in fact the score can range from 100% to -100%)!
* In Ireland, you can also be "awarded" an NG, which stands variously for No Grade or Not Gradable (with schoolyard parlance giving the meaning as No Good), meaning that you performed so badly that you don't even deserve an F.
* Most US universities allow a grade of "I", meaning "incomplete." However, this is usually just a temporary placeholder, indicating the student has a certain amount of time to make up for missed work. If that is not done then the grade converts to an F.
** If you really screw up badly before or after midterms, some professors will encourage you to withdraw from the class since you stand no chance of getting enough high grades to make the final grade of the class a passing grade. A W is always better than having an F, since a W usually has no effect on the GPA.
** "X" means "No Basis for Grade". Awarding this grade requires intervention from the campus ombudspeople.
** Most standardized tests with a grading system will have some kind of "ungraded" designation, like the "hyphen" on the AP exams, which is what you get if, for instance, you leave the multiple-choice section blank and draw a rocket ship on the essay paper.
** If a professor's rubric includes docking the final grade a few percentage points for missed classes, and if you do sufficiently poorly on your class work as well, it's quite possible to wind up with a final percentage that's less than zero. The final ''grade'' will still probably be counted as an F, but your score is a negative number.
** In some universities, if you receive a failing grade as a punishment for cheating or plagiarism, the grade may show up on your transcript as an "XF" or "FF" to indicate that you were flunked for violating academic integrity. This is generally considered even worse than failing just for not knowing the material. Ironically, some students have actually requested their schools adopt this grade so that the regular Fs on their transcripts wouldn't be mistaken for dishonesty.
** In some cases in college, you can be given a "WI" or "Withdraw--Instructor." This is for cases where it's past the deadline to drop or withdraw from the class normally (which wouldn't even appear on a transcript on the former case or as just "W" on the latter, neither of which affect GPA), but something else happens that would prevent you from finishing the course as normal(such as a medical emergency). By granting this, the teacher is basically saying "I won't pass or fail the student because I know this isn't their fault." Unlike a drop or normal withdrawal, this carries a much lower chance of harming your financial aid eligibility. Some more benevolent teachers will offer these to students that are really struggling near the end of the course, so they can try again without any harm to their GPA.
* In Hong Kong, there is also [[http://en.wikipedia.org/wiki/Academic_grading_in_Hong_Kong#Hong_Kong_Certificate_of_Education_Examination_and_Hong_Kong_Advanced_Level_Examination a "U" (or "UNCL", as known as Unclassified) grade]] which is considered [[FateWorseThanDeath worse than an "F"]]. You'll get this grade if you write/draw anything irrelevant to the exam, or turning in a blank paper.
* There is, in some Canadian Universities, the FD. Fail with Dishonesty. You plagiarized or cheated in one way or another, [[NoFairCheating and you get this S.O.B on your record]].
** At the [[http://ugradcalendar.uwaterloo.ca/page/uWaterloo-Grading-System University of Waterloo]], it was once possible (before 2001) to get a literal "F-minus" grade for anything 34% and below. Now they just use percentage grades for everything.
* In post-USSR Russia, grades are in numbers, with 5 being the highest, and 2 being the lowest. Getting a 1 requires something beyond just not attempting to read whatever is being tested. In UsefulNotes/TsaristRussia, however, it was officially used, and some ''very'' miffed teachers even used 0, but that required something above and beyond the call of stupidity.
** There's also Not Graded grade, which is commonly used to give the students a LastSecondChance.
* In some NYC colleges, students can get a WU. Unofficial Withdrawal. This only happens if you get excessive amounts of absent marks in a class without any excuse. This is worse than an F since an F shows you at least attended your classes somewhat while a WU can screw you over in registration for classes and is a pain in the ass to take care of.
* While "F" is often the lowest ''final'' grade an individual can receive for a course, for individual assignments where letter grades are equivalent to points that ultimately lead to the final grades many teachers are known for going below the standard "F" which usually is around 60 or 65 points out of 100. On something like a multiple choice test, going by the proportion correct makes sense, but on (for example) papers, there may be a conversion table for non-F letter grades, while F covers a broad range from "bad paper" to "turned in a blank paper, or obscene drawings, or..."
* In the Caribbean countries that are under the CARICOM (Caribbean Community), there are two major final exams for differing grade levels in secondary schools, namely the 11th grade and the 12th (or 13th) grade (known as sixth form). The examinations are officially named as the Caribbean Secondary Education Certificate (CSEC) and the Caribbean Advanced Proficiency Examination (CAPE) respectively. While the grade levels range from I-V, with I being the highest and V being the lowest, there is a U grade which stands for "ungraded", meaning that the examination was ungraded for a particular reason, usually due to the non-completion of the internal school-based assessment done within the final year, which is always a slight percentage of the final grade, ranging from 20% to 60%.
* In Poland school grades range from 1 (the worst) to 6 (the best), but at least some institutions use 0 for "ungraded". In college it's from 2 to 5 (oddly, 1 is not an option) and while halves are allowed, you can't get a 2.5 (no pluses or minuses involved), so basically there are 6 possible grades anyway.
* Academic dishonesty nets you two F's and an expulsion in most American colleges.
* Some elementary schools use(d) this scale: E, S+, S, S- and N (Excellent, Satisfactory +, Satisfactory, Satisfactory -, Needs Improvement).
** In Ontario, elementary schools (and recently even high schools) use E, G, S, N (Excellent, Good, Satisfactory, Needs Improvement) not for grades, but for a section called "Learning Skills".
** In New Jersey, for elementary schools only, the scale went VG, G, S, M, U (for Very Good, Good, Satisfactory, Minimal, Unsatisfactory) at least during TheNineties. Middle school and higher uses the standard system, however.
** There are other elementary school systems that don't use letter grades at all. A check mark indicates satisfactory performance, with a check-plus for excellent work, and a check-minus for not so hot.
* In Mexico, the highest grade you can legally get is 10 (or 100% using percentiles instead) while a 5 (50%) is considered a reprobatory grade, but some schools can grade a student below five to one, and sometimes '''negative grades.'''
** In Colombia the scale is from 1 to 5, the first one being the lowest possible; however (and this is depending on the teacher more than the system), a teacher can put a 0 if a student, let's say, cheat or threaten to lower decimal points of the grade; combine the two and you get a negative grade.
* In France, the grades usually go from 1 to something (usually 10, 20 or 40), 1 being the lowest (or 0.5/0.25 if the teacher uses decimals), with special notes such as "ABS" or blank for absent (which means you can maybe try again if you have a solid motive and a proof, such as hospitalization or the death/funeral of a relative). You get 0 by either [[EpicFail writing a truckload of nonsense/something utterly irrelevant]], cheating, bothering other students/children during the exam or not respecting the conditions of the exam or the school rules. With 3 or 4 exams per subject per trimester, getting a 0 in a whole subject during a year means either you're [[TheDitz Ralph Wiggum]], trying to sabotage your year or need help (a pupil or student with suddenly dropping grades is an excellent sign that [[{{Pun}} something doesn't add up]]...).
** Usually French schools score students out of a max of 20 but ''never'' award anyone better than a 19 out of 20, because perfection is impossible, and so the highest score one can get is 19/20
* In France, some teachers, especially in primary school, can remove one grade for talin (because the pupil can whispered the right answer , but the teacher can't prove that pupil is whispered the right answer ). IF your grade is zero originally, you can grade -1/10 or -1/20
* The lowest grade in the Danish grading system is -3.
* In New Zealand, grades under the NCEA system at high school are N, A, M, and E (Not Achieved, Achieved, Merit, Excellence), with N being the fail grade and the rest being passing grades. There is also an SNA grade (standard not attempted) if you leave your exam paper blank; this is worse than an N, but better in that it doesn't appear on your academic record. A DNS grade (did not sit) meanwhile is even worse; it means you didn't even turn up to the exam (and you didn't have a good enough excuse to get compassionate consideration).
* In Germany, grades go from 1 to 6, optionally with + or - added. 6 is the worst, 6- doesn't exist but is sometimes mentioned in the sense of this trope.
* Venezuelan grading on High School and most superior education institutions goes from 01 to 20 points, with "10" (or, technically, 9,5, since the grades round up) as the passing grade. Some teachers are not afraid to give full zeroes for the most spectacular failures. On one famous university, it was well known the anecdote of a Logic teacher infamous for his harsh grading who once handed a corrected exam without a grade, only some curve marks in the corners of the paper. When the student complained about his lack of grades and the strange marks, the teacher answered "oh, is that the zero you earned was so big it didn't fit on the paper."
* The inverse of this trope is slightly easier. It is possible to get more than 100% on a paper if you do extra credit or something worthy of being considered extra credit. This won't result in getting an A plus plus per se, though.
* Israeli comedian Shalom Asayag once said he broke a world record in lowest grade possible, ‘earning’ a -10 on a test he decided not to do after showing up, losing the extra 10 points because his school required that students bring a notebook documenting the tests they took, and he forgot to bring it.
* At Lancaster University, the grading system is based on that of the US (with grades A-D, with pluses and minuses, and then an F failing grade). However, the F grade here is subdivided into F1, F2, F3, and F4. An F1 indicates a poor grasp of the subject. An F3 is about the worst you can do while still submitting actual work. An F4 indicates that you either a) talked about a completely different subject on the exam, b) submitted no actual work, or c) submitted the work more than three days late without an extension.
* At some point in Dutch high school, there will be no more grammar and spelling rules to teach. At that moment some teachers might resort to harsher and harsher grading,for example test of 50+ questions with a 0.5/10 taken from your score with every mistake. This results in theoretical possibilities of getting scores like -16/10, but you wouldn't actually gave gotten so far if you're so bad at Dutch.
* Hungary has grades from 1 (worst) to 5 (best). But to reward an absolute null-effort, some teachers tend to award 0s. Even though it will officially be entered into the register as a 1, teachers have considerable freedom in determining the end-of-semester and end-of-year grades, so some of these zeroes will indeed be counted as zeroes when those teachers calculate the weighted average. (Similarly, 5* grades given for perfect tests might be counted as 5.5 or 6.)
