CLEP Biology FAQs
- The CLEP Biology exam tests your knowledge of biological sciences, organized in molecular and cellular biology, organismal biology, and population biology—helping you receive college credit for a fraction of the cost of traditional courses. The knowledge of biology required for this test may be expertise you already possess or can freshen up on. Abilities tested on the test are:

- The Biology CLEP exam is regarded as a challenging test, meaning it may be difficult for test takers without prior life science experience. For students who have taken biology classes and have ardently studied, the Biology CLEP test is more of a review of previous knowledge rather than an introduction to entirely new concepts. With that being said, a well-structured study plan with time set aside to prepare for the CLEP Biology exam gives you an advantage in achieving the best possible score. Set realistic study goals and visualize your success along the way.
- Students who want to gain college credit in biology without taking a class can take the CLEP Biology exam. CLEP exams provide a valuable opportunity to a wide variety of people seeking to save money while earning college credit. Tests assess students’ knowledge of various academic subjects. Learners that benefit from CLEP include:
- Home-schoolers—allowing the student the ability to demonstrate their knowledge and mastery of a specific subject while gaining college credit

- Adult learners—allowing those who plan to return to school after a break or pursue education for the first time the ability to save money and time

Students can take various exams on entry-level collegiate topics to bypass these courses in college or university. Does this sound familiar? That may be because many students take CLEP tests with DSST tests. While both offer college credit, CLEP tests offer testing in mainstream subjects, while DSST test subjects are more specialized.

While everyone is different, Peterson’s recommends at least 6 weeks of Biology CLEP test prep for test day. In those six weeks, Peterson’s CLEP Biology test prep prepares you for the questions you can expect on the exam with a pretest, two online practice tests, and an exam content overview.
