Admission to AA programs has gotten very competitive over the last few years. I'm not trying to discourage you, but I applied two years in a row with a 3.59 GPA and couldn't get into Nova, Emory, or South. Having a somewhat low quantitative GRE score probably didn't help my chances, either.

However, if you are just a sophomore, it isn't too late for you to switch majors and not really lose much time (in terms of semesters). If I were you, I would go ahead and change majors to nursing and set your sights on becoming a CRNA. There are many more CRNA programs throughout the country, so you have much higher chances of being accepted to at least one of them. CRNA's were recently awarded the right to be paid by CMS for pain medicine procedures at the physician rate, and of course, CRNA's can work in any state in the country.

After my multiple AA program rejections, I finally decided to change directions (despite already having a bio degree) and set my goal to becoming a CRNA. I will be starting an accelerated nursing program next semester. Even though I'll have to work for a year as an ICU nurse, I think it will be worth the hassle. You probably don't want to hear anyone tell you to become a CRNA instead, but it's worth considering, especially if you're at risk for spending several years applying and not getting accepted to AA programs.
