Maybe, but if you are a successful AA, I think many schools would be willing to waive pre-req time limits. The MCAT on the other hand may be mandatory again, but, I'm sure you could get connected not to take that as well.
The only reason I would want to go to med school after being an AA would be that my life outside of work would be too boring...hahahaha, I hope that doesn't happen! My wifey better keep me entertained!
