If a student does not have a strong background chemistry and biology, or if their knowledge is a little rusty and could use some refreshing, a fundamentals guide to organic chemistry is an excellent way to get back into the swing of things. A guide will go over the different types of bonds, atomic structure, and cover the important topics associated with biology that the student will need to understand before entering an organic chemistry class. Furthermore, study guides are much cheaper than a tutor, taking another course, or a textbook. The guide is succinct, too, and will not cover unnecessary or ancillary topics that will not be relevant to an organic chemistry course.
