>>13284364calc 2 is one of the notoriously hard classes for people, if you never saw the material keeping up with it is hard, even more so if you have a sloppy math foundation in calc 1, trig and algebra
what problems tripped you up in the exams? did you get what they were trying to do in the homework? tutors and online lectures can help by explaining it in a different way than your normal professor. i would try to make sure i could create and solve every problem given to me off the top of my head and id make up my own problems for my own study beyond the homework. as soon as you feel like you get stuck doing this, write down where you're stuck and try to fill that gap of knowledge in. this could even include looking back at algebra shit
solving the problems at the simplest level is the first step, then you have to understand why it's solved that way and not another(esp with picking integral methods) you cant afford to just memorize formulas, it has to make sense why it's used. integral problems usually need you to find the easiest way to integrate first. you dont have to go deep on an analysis 1/2 level(feel free to tho if it helps).
mostly spitballing any advice that came to mind, i hope it helps somewhat
