I have to disagree with the other comments. I was like you my freshman year, and asked my advisors and a couple of professors if I can start studying for the mcat my freshman year. They all said no. Right now I am in the position of retaking the mcat. I really wish I did not take the advice, and bought TBR C/P books my freshman year, and used those as I studied for my classes. I really think I would have nailed it the first time. I would offer you a unpopular advice of buying TBR b/b and c/p books now, and work through them side by side with your classes. For cars, maybe take a ethics/humanities course that involves lots of analyzing of dense passages. When it comes time to study for a couple dedicated months, you will be golden. If you can do both, without dropping your gpa I really think it will help you in the long run.
