Kornphan,
I really do not know the answer to your first question, but I can give some information for your second question. I remember when I applied, I thought the same thing as you. It seems that USF has for some reason a reputation of being number oriented. However, I can tell you that this is not entirely true. I know of some people that had MCAT scores that would be considered subpar to many people and still were accepted. They did offset this though with an excellent GPA and lots of leadership experience. Of course always try to achieve the highest score possible, but don't let a score considered subpar by others, discourage your chances. Try to do your best in all areas of the application. Just remember if you make it to an interview, everything else takes a back seat. Also remember that schools publish their AVERAGE MCAT scores and GPAs. All florida schools seem to rely more heavily on GPA then the MCAT. Hope that answers some questions.
