>>7550491As someone that actually teaches at a university, ask your professors if you have questions about material, even if you think it's just a dumb or small question. In my experience, I would much rather have someone ask a "Dumb question" and learn a concept better than have them struggle because they think they're going to be a burden or something.
Not all faculty will be decent, but I can guarantee you that putting forth that bit of being actively involved in your education is going to say a lot about you to some of your instructors. It can't hurt to try.
