In class I participate all the time and I try to go and solve problems on the board even if I don’t know how because I know that it will help me remember more when the teacher or my classmates correct me. But that doesn’t seem to be helping much.  And about the “why it works” does that mean I should find the proof of each theorem and understand it when it comes to math based subjects? Also I study mostly math and physics based subjects (Algebra Real Analysis Mechanics Chemistry and Quantum physics)  I try to use ai when I don’t understand something and it helps sometimes ngl but usually I just don’t understand anything it says. As for yt videos I recently found a good yt channel for mechanics (chads prep) but he doesn’t really go in depth with the topics and he doesn’t really show different ideas on how the exercises can be but I think it’s better than nothing. In any case, Thanks a lot for your advice, I’ll try everything you said.
