When doing my GCSE's in year 11, first maths exam I was one mark off a B, second exam, one mark off a C. I was so goddamned annoyed (Averaged out at a C in maths for those americans who dont understand school system). (Minor note, anywhere between A*-C is considered a pass in GCSE's, with C being the national avg, anything below D is usually looked down upon, and it goes D,E,F,U (U being unclassified / not even worthy of an F).
Tell your teacher to give you all A+ or you tell the FBI what he/she did to you all those years ago......
Different school districts/systems. Some places don't use E, my school does, and they don't use F. E is pretty much F, either way you still lose credit for that course.
A- Apple worthy B- Bad C- Crappy D- Dumbass F- Fucking stupid Anagram me and my friends came up with in Middle School... Cherish school children, it doesn't last...
