@Reeses25,
Usually, when it comes to undergrad, get the best grades you can at the best possible school. It's also helpful to go where you can make good contacts. Often AA and even BA degrees don't matter much and can even be interchangeable when it comes to careers and graduate schools.
The main outliers where you should really stick to specific programs:
- Medicine - it might not have to be an actual pre-med program, but it really should be in the hard sciences so you're not playing catch up. That means biology or chemistry, with psychology as a third choice and physics as a distant fourth choice
- Medically-related fields - these are fields like nursing, physical therapy, etc. You'd probably have to take all of those classes anyway
- Engineering - you'll also be playing catch up if you don't get a BS in engineering
And... that's about it. Law, for example, lots of people seem to think you need a poli sci degree for it. You don't, and you'll do better in admissions when you have something else like philosophy (I did) or nursing (the top guy in my class was an RN before getting his JD) or anything else (I also went to school with Pat Quinn, who'd been a coach for the Flyers).
So, all that having been said, get your AA in the field where (a) you can get the best grades; (b ) you can make the best contacts; and (c ) save the most money when it comes to going for your BA.
