What if the highest grade I can get is a C, would it still be average?
a C is considered as the minimum pass rate for most employers and within peer groups/own feelings/school/ w/e lol, but the majority of people see C as a 'meh' kind of grade, knowing they could do better. It's kind of in the middle ish, not many people want to go lower than an E so its 'a b C d e' really...depends how you think x
Exactly. Everyone has their own expectations, so everyone has a different idea of what grades are bad, acceptable and good. It's just that, generally speaking, most people believe a C is the lowest acceptable pass, with Ds and below not really worth having and Bs and above good. This is because only Cs and above are included in government league tables and accepted for entry to sixth forms, colleges and unis.
My aunt who is a Art teacher told me that E is the national average and anything above that she classes brainy.
