I most likely will not be able to take any upper division biology courses in time for when I start MCAT prep. I’ll have chem biochem 1 completed, though, which I hear is all that the MCAT covers in terms of biochem. How much of a disadvantage will I be at with no micro, genetics, A&P, etc? How much of this material will I have to self-teach myself the summer before my MCAT test date?
