i got an A in college class, but what should I do with the old HW? I plan to take calc II.

Once your grades are posted to your transcript, then you cal I homework is useless. You review the last bit of cal I at the start of cal II, but unless you need your homework for review, it really won't do you any good. You may want to hold onto your notes, especially the sections on chain rule, product/quotient rule, integration, and taking derivatives and antiderivitives. It also wouldn't hurt to brush up on your trig (identities and formulas), if you aren't already good at them, before you start cal II.
