I'm getting a phd in roleplay so I don't need maths and English, am smart enough to make it my friend.
Nah but for real, exams... Are kinda needed, even if they aren't fair. You could remember something 5 minutes after the exam, but you just forgot it because, mind blank.
Exams are something that is required because you'd have giant bias if you were given a mark out of how "good" you were in class, and how "good" you did with your work.
It works, exams do work, but that's not saying they aren't unfair, which they are, but we have to accept that, because everyone is given the same chance as everyone else, and that's the way it's just gonna be.
