Chemistry is a cumulative subject. It builds on your previous knowledge, so you can't afford to get behind, or you'll soon be lost. For lecture, take the time to come prepared. This preparation should help you understand the lecture, and concentrate in class on the points that were confusing. During class, take notes about what goes on.
