I finished all my pre-req courses this past semester, and am taking biochm and animal phys next semester. Would it be better to take the MCAT at the end of this summer, while all the info from my pre-req courses is still fresh in my mind, or should I wait until after I've taken biochm and phys? I've heard biochm and phys help for the MCAT, but I think it would be difficult to keep up with studying during the semester. How much of an advantage does taking biochm and phys give you on the MCAT?
