Think it's possible to get through 3 calc classes if?

Honestly, I thought precal was a waste of time and in some ways more difficult than Calc I and didnt prepare me for Calc. I wouldn't take it again. I make a lot of little errors as well. You just need to double and triple check your answers on tests. As far as remembering everything, yeah that's hard... you might try & take all the Calc at a comm. college, sometimes they might set it up so you have a take home test or something.
