The problem with exams is that everyone has a bad experience with a poorly written one. Well-written exams will have questions that test students at different levels of understanding across the whole curriculum.

So a student who only understands the basics should be able to answer most of the easy questions and students who have a deeper understanding can answer the harder ones.

Well-written exams should feel pretty fair and leave students feeling like the result they got is proportional to the effort they put into studying the material (or at least how well they personally felt they understood the material).

Exams almost filtered me out of this industry before I even got started. I later went on to be a lead developer! I went to a rural high school with a poor math curriculum. I understood the concepts, but I was slow. When I got to undergrad, my first calc professor gave us a 60 question test with 50 minutes of allotted time. He told us if we couldn't do the problems fast enough we weren't cut out for the work and it would be better if we quit now. I've never felt more inadequate in my life. It's one of my only Ws.
