PASSING THE CLEP NATURAL SCIENCES EXAM
Congratulations! 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 focuses on what you need to know to succeed on the CLEP Natural Sciences exam, and will help you earn the college credit you deserve while reducing your tuition costs.
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 and Get Feedback:Assess your strengths and weaknesses. The score report from your online diagnostic exam gives you a fast way to pinpoint what you already know and where you need to spend more time studying.
Review with the Book: Armed with your diagnostic score report, review the parts of the book where you’re weak and study the answer explanations for the test questions you answered incorrectly.
Ensure You’re Ready for Test Day: After you’ve finished reviewing with the book, take our full-length practice tests. Review your score reports and re-study any topics you missed. We give you two full-length practice tests to ensure you’re confident and ready for test day.
THE REA STUDY CENTER
The best way to personalize your study plan 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.
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
Our full-length 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 Internet-based, we recommend you take at least one practice test online to simulate test-day conditions.
AN OVERVIEW OF THE EXAM
The CLEP Natural Sciences exam consists of approximately 120 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 freshman or sophomore general science survey course covering biology and physical science. It is meant for students who are non-science majors. The exam stresses basic facts and principles, as well as general theoretical approaches used by scientists.
The approximate breakdown of topics is as follows:
50% Biological Science
10% Origin and evolution of life, classification of organisms
10% Cell organization, cell division, chemical nature of the gene, bioenergetics, biosynthesis
20% Structure, function, and development in organisms; patterns of heredity
10% Concepts of population biology with emphasis on ecology
50% Physical Science
7% Atomic and nuclear structure and properties, elementary particles, nuclear reactions
10% Chemical elements, compounds and reactions, molecular structure and bonding
12% Heat, thermodynamics, and states of matter; classical mechanics; relativity
4% Electricity and magnetism, waves, light, and sound
7% The universe: galaxies, stars, the solar system
10% The Earth: atmosphere, hydrosphere, structure features, geologic processes, and history
