Practice to Mastery: AP(R) Chemistry Practice Exams gives you twelve full-length practice exams for AP(R) Chemistry: 804 original questions, every one with a full explanation or a point-by-point scoring guide. Each exam covers the whole course, from atomic structure to electrochemistry, so every sitting tells you how ready you are across all nine units.
WHAT IS INSIDE
12 full-length practice exams, each built to the published shape of the examination
Section I: 60 multiple-choice questions in 90 minutes, 50% of the score
Section II: 7 free-response questions in 105 minutes, 50% of the score (3 long questions worth 10 points and 4 short questions worth 4 points)
720 multiple-choice questions and 84 free-response questions in all
The same unit balance in every Section I, close to each unit's weight on the examination, with Units 3 and 8 weighted most
Reference pages with the constants, equations and atomic masses used throughout the book
EXAMS THAT FEEL LIKE THE REAL THING
In Section I the units are mixed and easy and hard questions are interleaved, just as on the examination, and several questions in each exam share a table or a figure. Every Section II includes a laboratory or experimental-design question, a drawing (a Lewis structure or a particulate diagram), a graph to read or sketch, calculations with units and significant figures, and questions that ask you to justify a claim. About a third of the multiple-choice questions and most free-response questions draw on two units at once, because the examination rewards exactly that.
EXPLANATIONS AND SCORING GUIDES
Part 2 of each exam follows immediately: the answer key, an explanation of all 60 multiple-choice questions, and a scoring guide for all 7 free-response questions.
Each explanation opens with a line naming the unit and topic of the question, and any second unit it draws on, so you can sort your mistakes by unit
Every calculation is worked step by step, with units carried through and answers given to the correct number of significant figures
Each explanation ends with a one-sentence Key point worth remembering
Each scoring guide awards one point at a time and states what earns the point, which answers are acceptable, and the most common reasons for losing it, with credit for later answers that are consistent with an earlier error
HOW TO USE IT
Take one exam as a baseline once most of the course has been taught, then one every one to two weeks, and keep the last few for timed practice in the final fortnight. Log each miss by unit; the units where your misses gather are the ones to study again. The preface includes a full plan for sitting, marking and reviewing each exam.
WHO IT IS FOR
Students preparing for the AP(R) Chemistry Exam who want realistic timed practice
Students who have finished a unit-by-unit review and want to test the whole course
Teachers looking for original full-length exams for mock examinations and review
Every question, answer choice, data set, figure, explanation and scoring guide in this book is original. It is the companion to Practice to Mastery: AP(R) Chemistry Workbook and repeats none of its questions: the workbook teaches a unit at a time; this book asks whether you can work the whole course under the clock.
