I believe you should take a year off and do every prereq you can get at a local college or university. a way to check that would be to go on a computer and pull up the local college, and the college you set your mind to long term. so for instance LTC (long term college) may have a prereq Bio 213 and maybe you LC (local college) has a Bio 217. you would call the LTC and say hey, does your Bio 213 line up with LC Bio 217. Most of the time they will say yes. It saves a LOT of money.
