When I went to school, I actually liked mathematics a lot because I never had to study for it outside of class. If I understood a concept, I could apply it, and practicing in the lectures was mostly enough.
In university, though, things changed a bit because I can't just go to a lecture and be fine anymore. You have to push yourself through it by doing lots of problems, reading, and learning the proofs from the lectures. Thinking deeply about everything, etc.
An unfortunate challenge I face is that regardless of whether you do all that and "actually" understand things, it's not enough to get the best possible grade (even though this "actual understanding" is the most important, and without it, nothing else can help you improve more).
To excel in an exam, you have to prepare specifically for the exam. For oral exams, I use flashcards and do well, but I dislike everything that is repetitive. It's such an unnatural way of learning, and I hate doing it.
In written exams, we have to solve exercises, while in oral exams, we have to reproduce the lecture. That is a huge difference in difficulty. I enjoyed solving exercises much more than learning the lecture by heart.
Why are oral exams about the lecture and written exams like exercises?
