Practice to Mastery

Eight units of AP® Biology practice - and an explanation for every question in all of them.AP® Biology rewards students who can reason with material rather than recall it, and reasoning is built by doing, with feedback, many times over. This workbook is 1,105 questions and roughly 174,000 words of explanation, arranged so the feedback arrives while the material is still fresh.WHAT IS INSIDE- 1,105 questions: 1,021 multiple-choice and 84 free-response.- Eight units, in the order the official course framework sets out: chemistry of life; cells; cellular energetics; cell communication and the cell cycle; heredity; gene expression and regulation; natural selection; and ecology.- Every multiple-choice question has a written explanation that teaches the idea rather than naming the right letter. Every free-response question has a point-by-point scoring guide, model-response guidance, and a note on what the question is really testing.- A full-length practice examination closes the book, built to the published format: 60 multiple-choice questions in 90 minutes and 6 free-response questions in 90 minutes worth 34 points. Its explanations go further still, adding a note on each wrong answer and a one-line key point.THE ANSWERS ARE WHERE YOU NEED THEMMost workbooks put every answer at the back. You finish a unit, flip two hundred pages, lose your place, and check the letters without reading anything.Here each unit is in two parts. Part 1 is the questions. Part 2 - the answer key, an explanation of every multiple-choice question, and a scoring guide for every free-response question - sits at the end of that same unit. You can work a unit and learn from it in one sitting.BUILT TO BE WORKED ALONGSIDE A COURSEWithin each unit the multiple-choice questions run in difficulty order, easy to hard, and every question carries a printed tag: EASY, MEDIUM or HARD. The tag appears again on the explanation. Missing several EASY questions in one topic tells you a topic has not landed; missing only HARD ones tells you your foundation is sound and you need harder practice.Because the exam rewards carrying an idea from one unit into another, many of the harder questions need two units at once - and two units are combined only where the official framework places both on the same big idea, so nothing here tests a connection the course does not make. Every unit also carries experimental and data-analysis questions, because that is how the real paper asks.COMPLETELY ORIGINALEvery question, data set, table and explanation in this book was written for it. No question is taken from, adapted from, or modeled on any released or secure College Board examination item, and no passage is reproduced from any textbook or other published source.WHO IT IS FORStudents taking AP® Biology or a first college course in general biology, working through the year rather than cramming at the end. For a full season of timed practice, the companion volume, Practice to Mastery: AP® Biology Practice Exams, is twelve complete papers - each one covering the entire course framework - and it shares no questions with this book.AP® is a registered trademark of the College Board.
