Anatomy is the bomb man! I love going to the lab, taking that scalpel up and carving that turkey up. It's fantastic. Beats the living hell out of sitting through a mind numbing lecture on topic x or, a yet another wonderfully wasteful session of PB-Hell.
At least with anatomy you can see the practicality of what you're learning. You get to understand how certain injuries cause real, physical pathology. It makes sense, and isn't as gray as almost anything else in medicine. It feels "real". I think similarly of histo - provides you with a solid foundation for learning the rest of the material. Those two classes seem like the only real world stuff we do, except for clinical skills.
It's all the disease and symptom stuff that gets to me. You wouldn't believe how many pages of notes I have that start with either "an approach to memorizing the ddx for this condition" or "condition y: etiology, incidence, pathology, clinical presentation, treatment, complications etc."
Wonderful.
