Here's the scale
and I would believe two months would be suffice, I've only studied for a month and a half, i did poorly on my two kaplan practice tests[22-25 respectively] and on every one of my AAMC's, I've scored a 35+.
My MCAT is in a few days, but from the AAMC tests, it looks like I'm ready, anywhere 33~ is good enough for me.
