60% is a c (just a pass, not special) 70%/75% is a B (Not to amazing but ehhh something) 80%/85% is an A (That's pretty good, something to kinda brag about, pretty hard) 90%/95% is an A* (Now that's hard as -blam!-, that's something to show off and brag about) Oh and the percentage boundaries my vary (that's why I have 2 boundary levels for most of the grades) depending on the exam board, subject, paper, unit. 50% is a D (These are all the grades which mean you have failed an exam) Then it can go to E, F, G, there might be a H Then U is given when you don't take the exam I think. That picture is inaccurate as -blam!-. Oh and if you fail an exam it is a big embarrasement and it makes it hard to get accepted into sixth forms/colleges and may even affect which Uni you go to so ye, it's a piss take.
