FYI precal has virtually nothing to do with the following calc 1 class. the only relation it has, that is utilized in class, is the sin, cos, tan of angles (in rad or deg). precal, as said above, is a strengthening of algebra, with a hint of derivitives and integrals. if you can clep out, do it. go straight to calc, if you love math, you won't need precal.
that being said, take as many core classes as you can, that you are SURE will transfer to the university of your choice. if there are some iffy classes, go to an advisor at the university or email/call them and ask them. if you can, and they say said iffy class is transferable, get that shit in writing no joke. after 3 years, I have realized advisors really try to **** you here. if it isn't in writing, they WILL BLAME you for not taking the appropriate class.
if you have all your cores or a majority knocked out, then start taking classes both toward your AA and if possible toward your BS or BA, whichever you ultimately want.
