Well an exam is a test of knowledge, I don't think these are really necessary because its just showing what you know, and what you don't know its unfair and unnecessary, if the exam is asking you something you don't know its unfair, because then if you know nothing about what the exam is asking, it could make you seem not smart. This could be unfair, but if an exam is giving at the end of the school year or semester, then it would be fine because it would just be a recap of everything you've learned.
