Students who do not keep up in their studying generally find that classroom lectures become less and less comprehensible as the semester goes along. Soon the classroom experience consists of taking notes without much understanding of the material that is being presented and discussed. For most students it is better to work a few problems each day than to work a large number of them in one session and not do any for the next week or two. Also, it is often desirable to rework problems in successive study periods, especially those that were difficult to solve the first time. It is a mistake to skip over problems that are difficult for you.
Problems usually require thought and effort.
You are not supposed to know the answer when you first read the problem. Problem solving is figuring out what an acceptable solution might be. While much of this course requires an understanding of concepts, a considerable amount of memorization is also necessary to perform well on tests and quizzes. Memorization of facts requires repeated exposure to the facts over a relatively short period of time. If you learn better in a group setting, establish a small group consisting of up to four compatible individuals who can meet on a regular basis.
