Need some advise

This may be difficult to understand, so please bear with me. Although I have accumulated enough credits to probably have a masters degree by now (a result of numerous major changes), I guess I would be considered a junior in the application process. I have already completed most of my pre-recs, with the exception of organic chem. At this point, my future plans are as follows. I will take organic I this spring along with other required courses for my major. In the summer, I plan on taking Orgo II with lab, an MCAT Kaplan course, and finally the MCAT in August. The major I chose requires me to complete numerous courses specific to the major. As a result, I will be unable to fit micro or biochem into my schedule. However, I am required to take numerous courses in physiology, i.e. anatomy and physiology I and II, general and advanced exercise physiology, and clinical exercise physiology. Not being able to take biochem, micro, or any other recommended course for that matter, and taking the MCAT in August, in my eyes, puts me at every disadvantage for acceptance. I guess I could put off another year and take those extra courses along with the April MCAT, but I'm Already 22 years old and don't really want to wait any longer.
Any advise, criticism, input, or anything would be appreciated. These are my current stats: University of Florida, overall GPA ~3.9, Sci GPA ~3.9, minimal volunteer hours, assisted in organ transplant research, and pending MRS research. I will also be completing a mandatory 16-week internship in a biomedical facility in the fall.
Thanks in advance. Oh yeah, sorry for the exceptionally long thread.

 

I was initially planning on taking the extra courses (biochem, micro) to strengthen my application, not necessarily to prepare for the MCAT.
