SDN Members don't see this ad. (About Ads) Ok So I have Guyton textbook and that is my primary source of reading to supplement with that I think that I will be using Ganong and Constanzo's Physiology (Purple book). Now I know that Physiology is an important subject for the boards and the steps so I wanted to know 1. I've noticed thas Ganong is very different from Guyton in its content like it includes information that I can't find in Guyton and vice - versa for Guyton. So should I confer both books to get a firm grasp on Physiology 2. If lets say that I could read from all three texts should I or is that like overkill? 3. Can someone give me a site or book which contains MCQ that medical physiology where I can practice from?? 4. How should I go about studying all three of the texts? Should I just read them all like 1 time? How will physiology get stuck in my mind so I don't forget it??
