<p>So I want to make sure my chemistry skills are very sharp before I head off to college next year, and I want to go over an OCW course. However, there are two chemistry courses that I can't decide between. 3.091SC is a scholar course so it has more resources, but 5.111 is particularly focused on biology and since I am interested in biochemistry, this course seemed really interesting. However, I don't have access to either textbook: the only textbook I have is Chemistry by Zumdahl (4th Edition)--not sure if this is a good chemistry textbook or not. So which course should I take? Has anyone had any experience with either?</p>
