Practice to Mastery

Twelve full-length exams. Every topic in the course, in every exam. A clear picture of where you stand before test day.

Practice to Mastery: AP® Environmental Science Practice Exams gives you 12 complete practice exams built to the format and timing of the current AP Environmental Science Exam, 996 original questions in all. Each exam covers every one of the 99 topics in the course framework, so any exam you take is a true test of the whole course, not just the units you studied last.

WHAT'S INSIDE

- 12 full-length practice exams, each with the same structure and timing as the real test.

- Section I: 80 multiple-choice questions in 90 minutes, worth 60 percent of the score. Questions stand alone or come in sets built on graphs, data tables, models, and short passages.

- Section II: 3 free-response questions in 70 minutes, worth 40 percent of the score, in the official order: Design an Investigation, Analyze and Interpret Quantitative Data, and Analyze an Environmental Problem and Propose a Solution Doing Calculations.

- Every exam covers all nine units, with the number of questions per unit following the official unit weightings.

- A complete answer key for each exam, placed right after the exam.

- A detailed explanation for every multiple-choice question, labeled with its unit and topic so you know exactly what to review.

- A point-by-point scoring guide for every free-response question, showing what earns each point, plus a complete example response.

- A score worksheet for each exam, with a unit-by-unit breakdown and an estimated score range.

EXPLANATIONS THAT TEACH

Each answer is explained clearly and completely: the reasoning, the science behind it, and every step of any calculation, with units shown at each stage. You learn not just which answer is right, but how to reach it on your own the next time.

HOW TO USE THIS BOOK

Take the first exam early to find your starting point. Use the unit and topic labels in the explanations to target your review, then take the next exam under timed conditions to measure your progress. Twelve exams give you enough practice to spread across the whole school year or to work through intensively in the final weeks before the exam.

WHO IT IS FOR

- High school students taking AP Environmental Science who want realistic, full-length practice.

- Teachers who need complete, original exams for mock-exam days, quizzes, and review.

ORIGINAL AND CAREFULLY CHECKED

All questions, scenarios, data, and figures in this book are original. Scientific facts and every numerical answer were checked for accuracy. Each exam uses its own scenarios, and answer choices are balanced so the correct answer cannot be guessed from its length or position.
