NOTE FROM THE AUTHOR

Dear Student,

Thank you for choosing this book to help you prepare for your AP Chemistry exam Knowledge is perishable, so consistent practice is crucial to your

success on the exam Practice problems and questions are the most efficient and effective way to reinforce your knowledge, comprehension, and

application of chemistry Your mistakes will identify areas that need

improvement

The best time to use this book is a few months before your AP Chemistry

exam (but even a few days prior will help) It is meant as a comprehensive

review and is most helpful after you’ve learned at least half of the AP

curriculum

The AP Chemistry exam is a timed exam, so you may want to introduce a

time restriction into your practice You will have 90 minutes to complete

60 multiple-choice questions (an average of 90 seconds per question) and 105 minutes to complete 3 long and 4 short free-response questions To practice questions with time restrictions, attempt a group of multiple-choice or free-response questions in a specific time period (e.g., 10 multiple-choice

questions in 15 minutes) The College Board suggests approximately 20

minutes for long free-response questions (3 questions × 20 minutes = 60 minutes) and 7 minutes for short free-response questions (4 questions × 7 minutes = 28 minutes with 17 minutes “to spare”

All of the questions in this book are “AP Chemistry-like,” but there are

some notable differences There are no long free-response questions.

Instead, several short free-response questions have been grouped together when they refer to the same data or phenomenon and should be treated like a long free-response question on the AP Chemistry exam The only difference

is that instead of being numbered 1a, 1b, 1c etc., they are simply given their own number For these questions, some answer explanations will give away the answers to later questions in the set and some questions later in the set will require answers from previous questions (as in the long free-response

questions) To avoid inadvertently obtaining answers to later questions,

answer all the grouped questions before looking at the answers, as if you were working on a long free-response question If a question requires an

answer from a previous question and you really want to be sure you’ve got it

right before you move on, check the answer but not the explanation Most

free-response questions are at the end of the chapter; however, you will find a few interspersed with the multiple-choice questions if they refer to a common data set with multiple-choice questions

If you guess on a question, even if you mostly worked out the answer using chemistry, mark that question for later review If you guessed

correctly, you may not remember to review the question and answer to clarify and reinforce the information When the topic comes up again, you may not guess as well!

In conjunction with this book visit the College Board website

(www.collegeboard.org) Make sure you do all of the practice questions the College Board has made available to students You can download the AP Chemistry Course Syllabus and use the section on the Big Ideas 1 to 6 as a study outline to help you narrow down what the exam will focus on Read all

of the “exclusion topics.” Even if you have no intention of reading any part of the curriculum, the AP Chemistry Course Syllabus will give you access to 43 multiple-choice practice questions with answers and free-response questions with scoring guidelines

Each year the College Board releases the free-response questions with

scoring rubrics You should become familiar with as many scoring rubrics

as you can, even if they are from exams administered prior to 2014 (when the

AP Chemistry exam underwent a major overhaul) They are all free to

download from the site The free-response rubrics (even from older exams) will help you get acquainted with the nuances of the point-earning system used with the free-response questions They provide important information to help you distinguish between a mediocre answer and an excellent one!

Be aware that the College Board has released at least one full-length

practice test that is only available to teachers Make sure you ask your

teacher to administer it to your class

Review your labs! Chemistry is a laboratory science, so expect to see a

significant number of questions related to labs on the AP exam

The AP Chemistry exam is 3 hours 15 minutes long It is composed of two

sections of equal point value Be familiar with the exam before you sit for it

so you can let your brain focus solely on the chemistry You will be supplied with reference materials that you can use on both sections

MULTIPLE-CHOICE SECTION

60 questions in 90 minutes

No calculator

4 answer choices

No ¼ -point penalty for incorrect answers

FREE-RESPONSE SECTION

3 long free-response questions

4 short free-response questions

90 minutes

Any programmable or graphing calculator allowed A four-function

calculator is allowed but not recommended

The College Board may make changes to the exam or its administration that may not be reflected in this version of the book, so please check the

College Board website for the most up-to-date information, especially

regarding test timing and calculator use The College Board wants those who are proficient in chemistry to do well on the AP Chemistry exam There is a lot of good information on their website, so check it out They offer some

excellent strategies for pacing yourself on the AP Chemistry exam on this

Good luck! Mina

I would like to thank my uncle, Dr John Simpson, for not only igniting

my love of science but for answering five million chemistry questions over the years!
