PASSING THE CLEP BIOLOGY EXAMCongratulations! You’re joining the millions of people who have discovered the value and educational advantage offered by the College Board’s College-Level Examination Program, or CLEP. This test prep covers everything you need to know about the CLEP Biology exam, and will help you earn the college credit you deserve while reducing your tuition costs.GETTING STARTED
There are many different ways to prepare for a CLEP exam. What’s best for you depends on how much time you have to study and how comfortable you are with the subject matter. To score your highest, you need a system that can be customized to fit you: your schedule, your learning style, and your current level of knowledge.This book, and the online tools that come with it, allow you to create a personalized study plan through three simple steps: assessment of your knowledge, targeted review of exam content, and reinforcement in the areas where you need the most help.Let’s get started and see how this system works.Test Yourself & Get Feedback
Score reports from your online diagnostic and practice tests give you a fast way to pinpoint what you already know and where you need to spend more time studying.Review with the Book
Study the topics tested on the CLEP exam. Targeted review chapters cover everything you need to know.Improve Your Score
Armed with your score reports, you can personalize your study plan. Review the parts of the book where you’re weakest and study the answer explanations for the test questions you answered incorrectly.THE REA STUDY CENTER
The best way to personalize your study plan and focus on your weaknesses is to get feedback on what you know and what you don’t know. At the online REA Study Center, you can access two types of assessment: a diagnostic exam and full-length practice exams. Each of these tools provides true-to-format questions and delivers a detailed score report that follows the topics set by the College Board.Diagnostic Exam
Before you begin your review with the book, take the online diagnostic exam. Use your score report to help evaluate your overall understanding of the subject, so you can focus your study on the topics where you need the most review.Full-Length Practice Exams
These practice tests give you the most complete picture of your strengths and weaknesses. After you’ve finished reviewing with the book, test what you’ve learned by taking the first of the two online practice exams. Review your score report, then go back and study any topics you missed. Take the second practice test to ensure you have mastered the material and are ready for test day.If you’re studying and don’t have Internet access, you can take the printed tests in the book. These are the same practice tests offered at the REA Study Center, but without the added benefits of timed testing conditions and diagnostic score reports. Because the actual exam is computer-based, we recommend you take at least one practice test online to simulate test-day conditions.AN OVERVIEW OF THE EXAM
The CLEP Biology exam consists of approximately 115 multiple-choice questions, each with five possible answer choices, to be answered in 90 minutes. The exam covers the material one would find in a college-level general biology course. The exam stresses the broad field of the biological sciences organized into three major areas:33% Molecular and Cellular Biology34% Organismal Biology33% Population BiologyFor a list of subtopics covered on the exam, visit the College Board website.ALL ABOUT THE CLEP PROGRAM
What is the CLEP?
CLEP is the most widely accepted credit-by-examination program in North America. CLEP exams are available in 33 subjects and test the material commonly required in an introductory-level college course.
