hi i rawdog my degree crying and screaming so idk how useful my tips will be but i think try not to skip classes/lectures and if u do, try to catch up asap with the lecture notes or recordings, do more practice questions & past exam papers if ur uni/school has that, consolidate ur understanding & knowledge regularly over the year, when revising in exam season prioritize understanding the core concepts (and the math skills) rly well first and then do it in detail, a lot of details can usully be derived from the core concepts anyway (like if i cant remember all the forumlae i remember the most important and the others can be derived.) dimensional analysis also helps w getting the form of equations right
