Practice to Mastery: AP® Calculus BC Practice Exams gives you twelve full-length practice exams built to the format of the AP Calculus BC Exam, with a detailed explanation for every multiple-choice question and a 9-point scoring guide for every free-response question.Each exam follows the published structure of the real one. Section I has 42 multiple-choice questions in 1 hour 40 minutes: 29 without a calculator and 13 with a graphing calculator. Section II has 6 free-response questions in 1 hour 30 minutes: 2 with a graphing calculator and 4 without. Every exam samples all ten course units in proportion to their weight on the exam, so the twelve exams are comparable and your scores show real progress from one exam to the next.Every exam includes the material only BC students are tested on: infinite series, Taylor and Maclaurin polynomials, error bounds, parametric equations, polar coordinates, vector-valued motion, improper integrals, integration by parts, partial fractions, Euler's method, logistic models, and arc length. Every Section II includes a series question and a parametric, polar, or vector question, along with at least two questions set in real-world contexts.What is inside:- 12 full-length practice exams: 576 original questions, 504 multiple choice and 72 free response- Calculator and no-calculator parts in both sections, matching the exam's calculator rules- Exam-style material throughout: graphs of f, f¿, and f¿, tables of values, slope fields, parametric and polar curves, region diagrams, and shared-stimulus question sets- A clear explanation of every multiple-choice question, labeled with its unit and topic- A 9-point scoring guide for every free-response question, with general scoring notes, point-by-point criteria (P1 to P9), notes on what earns credit, and a complete model solution- A score estimate after every exam that converts your results to an approximate AP score- A guide to the exam format, timing each part, scoring yourself honestly, and reviewing each exam by unit, by calculator use, and by question typeHow to use this book:Take each exam in one sitting under timed conditions. Score Section I with the answer key and Section II with the scoring guides, exactly as a reader would. Then sort what you missed: by unit, by calculator or no calculator, by procedure or concept, and by the BC-only question types. The pattern tells you where your next hour of study will count most. Spread the exams across the final months of the course, and save one or two for a final rehearsal.Every question in this book is original, and only the structure of the exam is modeled on the published format. Every answer, distractor, and numerical value was checked by computation, and every multiple-choice question was independently re-solved.This book is the companion to Practice to Mastery: AP® Calculus BC Workbook, which builds skill unit by unit with 1,407 practice problems. The two books share no questions.AP® and Advanced Placement® are registered trademarks of the College Board, which was not involved in the production of, and does not endorse, this product.
