I kind of made my load a little less demanding. 17 credits, taking Chemical biology, Psychology statistics, Sports nutrition, chem bio lab, classics independent readings, and an independent study in exercise physiology. The latter two i did not have to attend class for, which cut out on the class scheduling times that could interfere with mcat studying. Chem bio was time-intensive, but only for one day per week. psych stats, chem bio were just normal classes with normal loads. Sports nutrition was a pain in the butt, but again not quite as work intensive as other courses i've taken in the past. All throughout this time I also worked about 10 hours per week in the lab, and had crew practices/races. In the last couple weeks leading to the MCAT, I stopped going to work to prepare. I studied since January, because I'm a senior and had been away from a lot of the material for more than 2 years. I don't know if it helped that much or not, since the bulk of my prep came within the last two weeks.
