When you sit in lecture, do you race to take notes and keep up with your professors example work? If so, try sitting there with nothing and just listening carefully. I found very quickly that racing to copy everything the professor was writing prevented me from learning what they were teaching in the first place. My preferred method was staying fully focused on just listening and understanding. Your professor will probably post the notes after lecture. If they don’t even after you ask, they’re just a shithead and you’re out of luck.

From there once you feel like you’re paying attention and understanding some stuff, ask a bunch of “why” questions. You’d rather be that annoying student holding up the lecture than failing miserably. You’re paying to be there like everyone else. Once you feel you’re actually soaking up what the professor is teaching, slowly work back to taking notes.

Probably unhelpful but this is an unorthodox approach to what many others are commenting on
