I was wondering what you should be familiar with before taking Calculus II. I just finished the Calc I summer class and was wondering if I should go on to Calc II this summer or just go over Calc I some more... I mean I can solve all of the problems that were presented but we hardly had any proofs. Would it be better to wait until fall to start calc II and become comfortable with proofs or just do Calc II and pick things up as I go? How do you know if your ready . Will going on to Calc II help retain Calc I?
