About Scientific American Scientific American is at the heart of Nature Publishing Group’s consumer media division, meeting the needs of the general public. Founded in 1845, Scientific American is the longest continuously published magazine in the United States and the leading authoritative publication for science in the general media. In its history, 148 Nobel Prize scientists have contributed 240 articles to Scientific American, including Albert Einstein, Francis Crick, Stanley Prusiner, and Richard Axel. Together with scientificamerican.com and in translation in 14 languages around the world, it reaches more than 5 million consumers and scientists. Other titles include Scientific American Mind and Spektrum der Wissenschaft in Germany. Scientific American won a 2011 National Magazine Award for General Excellence.

Reasoning About the Design and Execution of Research (10% of questions) 4. Data-Based and Statistical Reasoning (10% of questions) The MCAT is a computer-based test (CBT) and is offered at Prometric centers during almost every month of the year. There are optional breaks between each section, and there is a lunch break between the second and third section of the exam. Register online for the MCAT at www.aamc.org/mcat . For further questions, contact the MCAT team at the Association of American Medical Colleges: MCAT Resource Center Association of American Medical Colleges (202) 828-0690 www.aamc.org/mcat mcat@aamc.org How This Book Was Created The Kaplan MCAT Review project began in November 2012 shortly after the release of the Preview Guide for the MCAT 2015 Exam, 2nd edition. Through thorough analysis by our staff psychometricians, we were able to analyze the relative yield of the different topics on the MCAT, and we began constructing tables of contents for the books of the Kaplan MCAT Review series. Writing of the books began in April 2013. A dedicated staff of 19 writers, 7 editors, and 32 proofreaders worked over 5000 combined hours to produce these books. The format of the books was heavily influenced by weekly meetings with Kaplan’s learning-science team. These books were submitted for publication in July 2014. For any updates after this date, please visit www.kaplanmcat.com . The information presented in these books covers everything listed on the official MCAT content lists—nothing more, nothing less. Every topic in these lists is covered in the same level of detail as is common to the undergraduate and postbaccalaureate classes that are considered prerequisites for the MCAT. Note that your premedical classes may cover topics not discussed in these books, or they may go into more depth than these books do. Additional exposure to science content is never a bad thing, but recognize that all of the content knowledge you are expected to have walking in on Test Day is covered in these books. If you have any questions about the content presented here, email KaplanMCATfeedback@kaplan.com . For other questions not related to content, email booksupport@kaplan.com . Each book has been vetted through at least six rounds of review. To that end, the information presented is these books is true and accurate to the best of our knowledge. Still, your feedback helps us improve our prep materials. Please notify us of any inaccuracies or errors in the books by sending an email to KaplanMCATfeedback@kaplan.com . Using This Book Kaplan MCAT Physics and Math Review, along with the other six books in the Kaplan MCAT Review series, brings the Kaplan classroom experience to you—right in your home, at your convenience. This book offers the same Kaplan content review, strategies, and practice that make Kaplan the #1 choice for MCAT prep. After all, twice as many doctors prepared with Kaplan for the MCAT than with any other course. This book is designed to help you review the physics and math topics covered on the MCAT. Please understand that content review—no matter how thorough—is not sufficient preparation for the MCAT! The MCAT tests not only your science knowledge but also your critical reading, reasoning, and problem-solving skills. Do not assume that simply memorizing the contents of this book will earn you high scores on Test Day; to maximize your scores, you must also improve your reading and test-taking skills through MCAT-style questions and practice tests. MCAT CONCEPT CHECKS At the end of each section, you’ll find a few open-ended questions that you can use to assess your mastery of the material. These MCAT Concept Checks were introduced after multiple conversations with Kaplan’s learning-science team. Research has demonstrated repeatedly that introspection and self-analysis improve mastery, retention, and recall of material. Complete these MCAT Concept Checks to ensure that you’ve got the key points from each section before moving on! PRACTICE QUESTIONS At the end of each chapter, you’ll find 15 MCAT-style practice questions. These are designed to help you assess your understanding of the chapter you just read. Most of these questions focus on the first of the Scientific Inquiry and Reasoning Skills (Knowledge of Scientific Concepts and Principles), although there are occasional questions that fall into the second or fourth SIRS (Scientific Reasoning and Problem-Solving, and Data-Based and Statistical Reasoning, respectively). This book also contains a full chapter each for two of the SIRS: Chapter 11 (Reasoning about the Design and Execution of Research) and Chapter 12 (Data-Based and Statistical Reasoning).
