Biology 101: Intro to Biology is designed to be used to prepare you to earn real college credit by passing the Biology CLEP exam.
This course covers topics that are included on the exam, such as genetics, physiology, plant and animal biology, ecology and evolution.
Use it to help you learn what you need to know about biology topics to succeed on the exam.
The biology instructors are experienced and knowledgeable educators who have put together comprehensive video lessons in categories ranging from Mendel’s first law to the anatomy of the brain.
Each category is broken down into smaller chapters that will cover topics more in-depth.
These video lessons make learning fun and interesting. You get the aid of self-graded quizzes and practice tests to allow you to gauge how much you have learned.
