I recommend you learn the basic calculus topics (derivatives and integrals) well ahead of your class cuz the applications should be fairly easy to pick up on if you’re not wasting time learning the basic stuff (that’s what I did at least)
Applications or just basic derivatives?
The derivatives don’t get that hard in tests and I’d say just use the textbook for that
Applications idk use trials I have no clue what the advanced syllabus is
