You're going to have to be very diligent about studying biology, because intro to Bio isn't going to cut it going in; the MCAT had questions the topics of which weren't emphasized until higher-level biology courses (like biochem and genetics).
Also, I'm not sure what kind of physics in high school you took, but sub-AP courses will be no help whatsoever. Depending on what level of AP Physics you take in high school, you may or may not have gone over electromagnetism and optics, both of which will DEFINITELY be on the MCAT.
You might be able to slide by with only organic 1, but I have heard of some organic 2 questions on the MCAT (don't remember specifically about my own).
Finally, you're going to want to brush up on those typing skills if you want to get a passable grade on the writing section.
