Hmm, here we go (from most difficult to least): 1. Pharmacology 2. Physiology Lecture 3. Physiology Lab 4. Microbiology 5. Anatomy Lecture 6. Anatomy Lab I've always considered anatomy to be fairly easy to learn, at least compared to the physiology counterparts which I consider to be of moderate difficulty. Microbiology is sort of challenging, but not terrible or anything. Pharmacology is a fairly demanding class- there's just a very large amount of information to take in. Hope that helps! --Ari Ballaban
