The College Level Examination Program (CLEP) enables students to demonstrate college-level achievement and earn college credit in various subject areas based on knowledge acquired through self-study, high school and adult courses, or through professional means. The CLEP Biology Passbook(R) prepares you by sharpening knowledge of the skills and concepts necessary to succeed on the upcoming exam and the college courses that follow. It provides a series of informational texts as well as hundreds of questions and answers in the areas that will likely be covered on your upcoming exam, including but not limited to: molecular and cellular biology; genes; reproduction and development; principles of ecology; social biology; and more.
