I am going to the University of Oklahoma and want to finish my pre-pharmacy classes in 3 years but will have to take the PCAT at the end of the second year. So would it be hard to take Organic Chemistry II and lab (5 hours), Fundamentals of Microbiology and lab (5 hours) and Human Physiology and lab (4 hours) my second semester of my sophomore year? Do those labs make it seem like more credit hours and work than they really are because they last 4 hours but only count for 2? Also is 6 weeks enough time to study for the PCAT? Thanks.
