I took the MCAT in August and got a 21. This is pretty much my last chance. Last time I started studying too late because I was finishing up my Masters. I apparently also didn't put enough time into it. I'm studying on my own as I can't afford to take one of the courses (some of them literally cost more than I make in a year). But I digress. I'm studying primarily using Khan Academy's MCAT 2015 videos and the Kaplan MCAT 2015 ebooks. Is there anything I should be doing or should not be doing to improve my score? It's looking like I'm going to need something greater than a 500 on the new MCAT? Or is that different b/c it's a bell curve? I've not yet seen any schools post their requirements for MCAT 2015. I'm primarily looking at DO schools b/c they tend to have lower GPA and MCAT requirements.
