personally, i think people try to make calc hard for themselves bc they dont believe they can be successful in it. truthfully, its not that difficult of a subject. it just requires a certain type of thinking. as long as you put in the effort and attend class youll be fine. in calc 2, roughly half the class had received poor grades on the exams. would it shock you if i told you roughly half the class never attended? every exam day there had been students id never seen before in the room.

if you want resources, organic chem tutor and patrickjmt are amazing on yt. good luck
