Scoring well on College-Level Examination Program (CLEP) Biology is important for your ability to bypass taking the class and earn college credit. To achieve a high score, you need to develop skills to properly apply the knowledge you have and quickly choose the correct answer. You must solve numerous practice questions that represent the style and content of the CLEP questions. Understanding key science concepts is more valuable than memorizing terms. This book provides over 1,550 biology practice questions that test your knowledge of all Biology topics covered in an undergraduate biology course and tested on CLEP. In the second part of the book, you will find answer keys and detailed explanations to questions, except those that are self explanatory. These explanations discuss why the answer is correct and - more importantly - why another answer that may have seemed correct is the wrong choice. The explanations include the foundations and details of important science topics needed to answer related questions on CLEP. By reading these explanations carefully and understanding how they apply to solving the question, you will learn important biology concepts and the relationships between them. This will prepare you for CLEP Biology exam and will significantly improve your score. All the questions are prepared by our science editors who possess extensive credentials and are educated in top colleges and universities. Our editors are experts on teaching sciences, preparing students for standardized science tests and have coached thousands of undergraduate and graduate school applicants on admission strategies.
