From the Author Last updated?December 16, 2016.?Used books may have outdated content.?We make content updates?every 4-6 weeks?based on customers' comments, editorial input and latest test changes. The most current version is only available directly from Amazon, Barnes & Noble and Sterling Test Prep web store.???Scoring well on the MCAT is extremely important for admission into medical school.? To achieve a high MCAT score, you need to develop skills to properly apply the knowledge you have and quickly choose the correct answer. ?Understanding key concepts, having the ability to extract information from the passages and distinguishing between similar answer choices is more valuable than simply memorizing terms.This book provides over 1,200 chemistry practice questions that test your knowledge of all MCAT General Chemistry topics.? At the back of the book, you will find answer keys (use them to verify your answers) and explanations to questions.??These explanations provide step-by-step solutions for quantitative questions and detailed explanations for conceptual questions.????The explanations in this book also cover the foundations of chemistry topics needed to answer related questions on the test.? By reading these explanations carefully and understanding how they apply to solving the question, you will learn important general chemistry concepts and the relationships between them.? This will prepare you for the test and you will significantly increase your score. ??Our preparation materials will help you succeed by scoring well on the MCAT.? All the content of our publications is prepared by our editors who possess extensive credentials, are educated in top colleges and universities and have been admitted to medical school with stellar MCAT scores.? Our editors are experts on teaching, preparing students for the MCAT and have coached thousands of premeds on admission strategies.
