Hate to be the bearer of bad new but unless they have changed the rules in the last two years you have to score at least a 30 the first time you take the MCAT. When I was applying a couple of years ago you had to have at least a 3.6 gpa and a 30 MCAT the first time you took it with no subsection below 10. Just do a little research and read the fine print before you do this, but don't worry, with a 31 and 4.0, you'll definitely get into UAB as a regular applicant as long as you're in-state.
