Ok so I’m a bit worried. I transferred universities and start this upcoming spring. At my current uni I had all my math done. I did statistics, pre-calculus, and applied calculus (I’m a bio major). I heard applied was easier than calculus 1 and it counted as credit there so I did it. Looking back I regret this decision because now at my new university they want me to have calculus 2 and I never took 1. I made As in both my calculus classes but it’s been awhile since I’ve taken them. Any advice for what I should go back and refresh on/ things I should DEFINITELY know BEFORE I start calculus 2? I want to start working problems and practicing so I’m not super far behind to give myself the best chance. TIA :,)
