When I got out of the MCAT, I had no idea at all what I got. I figured anywhere from 29-36. I had been getting 35+ on my practices, but I was wiped out by the end of the test (took the 8-hour version in '05), and my head wasn't quite in it when the biological sciences came up.
I ended up with a 33, so I guess I was close on my guess, but that might just have been because I had taken a bunch of practice tests.
Man I wasn't getting no 35+ on practice exams lol. So shall see how it goes.
I appreciate your desire and will still to attend medical school at your age, I hope I can have the same drive when I get to your age.
