I know that nobody has responded yet, but I'm also concerned about how much I'll be able to study for the MCAT next spring considering that I'll be taking 8 hours of credits, doing ~10 hours of research per week, along with trying to volunteer just as much as I have been this semester. I feel like either my MCAT studying or volunteering hours will suffer and these also make me feel like it could be advantageous to take another year.
