No Gap Year?

How viable would it be to not take a gap year? I wont have completed physics II and possibly sociology/genetics by the time I take the MCAT, and I want to obviously score well, but I also really don't want to take a gap year. I would self study for about 2 months. DO MCAT scores are typically around the 502 mark, so that gives a bit more wiggle room I suppose. So from past applicants, what is your experience with the MCAT and app cycle without a gap year? Thanks!
