I would not take something that I need to truly learn over the summer. It's just not good. If you insist on doing it, I'd take the A&P part 2 over Summer I, Diet and Nutrition over Summer II, and the 11-week Pharmacology. If you want time to come up for air, I'd eliminate the Diet and Nutrition, so your Summer II is lighter. It will give you time to catch up on Pharmacology if you fell behind during the first half, and maybe a chance to breathe some fresh air before jumping into Fall.
