Thanks for the replies. It does seem that most people find anatomy the easiest since it is mostly memorization and microbiology the hardest. What exactly makes microbiology so much harder? I don't understand why some schools separate anatomy and physiology. At my school, we have a 12 week summer session where they offer physiology for the first 6 weeks then anatomy for the last 6 weeks. You would think they would do it the other way around, but they don't. For those that took anatomy and physiology as separate classes, but in the same semester, did the class coincide with each other so that you were learning the about the structures and their functions at the same time? It really does seem that a combined anatomy and physiology works best. But alas, there's nothing I can do about that. @Sayfasa- Why do you not recommend taking physiology and microbiology together? I was actually originally planning to take all three classes next semester of Fall 2011 (with no other classes), but I might be biting more off than I can chew. I could take the 12 week summer course plan, and leave microbiology for the fall, but a 6 week course on each seems way too fast paced for me. Not only that, I would have to pay $1,000+ of my own money after financial aid. If I take them all in the fall, I don't have to pay extra for those classes, and I have 3+ months to learn the subjects. Are there any thoughts on which plan is better-- the less of the two evils? It seems like I'm rushing to finish these classes, which I am to be honest, and I know it might bite me back in the end, but I honestly don't want to spend more than 1.5 years on prerequisites. Okay, I will stop rambling now. I appreciate any advice/insight you guys can provide.
