@Kotylynne- I liked Advanced Physiology myself. It picks up where APHY 101 and 102 left off, so it was kind of cool to brush up on some of the 101 concepts that I hadn't seen for awhile. It's pretty in depth too, so you end up touching on some of your chemistry knowledge too (cell-membrane transport, electro-chemical gradients, etc). I asked one of the professors if advanced physio or the microbiology would prepare me further on down the road, and he suggested advanced physiology. I recommend taking it with Dr. Burgess. He's actually a Chiropractor and seems to really know his stuff and how things work in the real world. He's fair and there are a couple opportunities for extra credit too. If you have to miss a test, he lets you make up one missed test at the end of the semester.
