The average MCAT score of those accepted was ~8.7 when I applied 2 years ago, and I've been told that it's gone up slightly since then but I haven't seen any numbers, if you'd like me to get more specific, I can try to find out after the MLK holiday
You're probably going to need to call the admissions office to ask. I have never been told or asked about this particular point before. The admissions people are very nice & are quite used to addressing calls from applicants, so it won't be like you're annoying them by asking. 🙂
*btw: the stats hernandez posted are from the class in ahead of mine (2006). I know that my class has higher stats, and I believe that 2007 does, too. I haven't heard anything official from 2008. I know that the school is trying to increase the averages. 🙂
