Organic Chemistry isn't as hard as people make it out to be. It only becomes difficult when you are cramming for your exams. The best advice is to always be on top of the lecture and review what you learn every day if not every other day. My Organic Chemistry I was hard because I always crammed it into a day or two before the exam. However, for my Organic Chemistry II course, I took the honors section. In this section, we always had a quiz in each class that made us keep up with the materials. Thus, when it came to the exam time, I had already about 90% of the materials memorized and they had become second-hand.
