Physiology for me was almost no memorization. My professor was a big fan of conceptual 2 or 3 step questions. The thing that I found helpful, which I think can apply to any class, is find someone you can teach the material to. The more I explain the concepts or mechanisms to someone, the more I solidify those concepts in my mind. Always try to understand why something happens. By applying your knowledge of gen bio, you should be able to figure out the "why" to almost everything. My class was A&P, the lecture was the P and the lab was the A. Anatomy itself was all rote memorization. If you have an anatomy lab, spend time studying the cadaver. Often times, students would study from the book or online dissection tool, which doesn't account for anatomical differences or the specific layout of the anatomy in the cadaver they were being tested on.
