degrees in Bioengineering: Pre-Med and Psychology. After
graduation, she moved to Cincinnati, OH for a year where she
certified to tutor online and was promoted to Master Tutor. She
is currently residing in Philadelphia, PA where she is a graduate
student at Temple University, working on her Ph.D. in Urban
Education. She is certified to teach and tutor numerous
Advanced Placement courses as well as the PSAT, SAT, ACT,
LSAT, GRE, and MCAT. In her spare time, Bikem enjoys
spending time with her dog, Gary, and her nieces, Laila and
Serra.
Chris Knuth have been with the Princeton Review for 9 years
and has been teaching Math since the 5th grade through
various tutoring organizations and classes. He is certified to
teach various Advanced Placement courses as well as SAT,
ACT, GMAT, GRE, LSAT, DAT, OAT, PSAT, SSAT, and ISEE. He
considers Calculus to be his favorite level of Math. Chris would
like to thank his family for their unwavering support and always
being the “wind in my sail” and give a very special thank you to

EXPECTATIONS
Your route to a high score on the AP Calculus Exam depends a
lot on how you plan to use this book. Start thinking about your
plan by responding to the following questions.
1. Rate your level of confidence about your knowledge of the
content tested by the AP Calculus Exam:
A. Very confident—I know it all
B. I’m pretty confident, but there are topics for which I
could use help
C. Not confident—I need quite a bit of support
D. I’m not sure
2. If you have a goal score in mind, circle your goal score for
the AP Calculus Exam: 3. What do you expect to learn from this book? Circle all that
apply to you.
A. A general overview of the test and what to expect
B. Strategies for how to approach the test
C. The content tested by this exam
D. I’m not sure yet YOUR GUIDE TO USING THIS BOOK
This book is organized to provide as much—or as little—
support as you need, so you can use this book in whatever way
will be most helpful for improving your score on the AP
Calculus Exam.
The remainder of Part One will provide guidance on how
to use this book and help you determine your strengths and
weaknesses.
Part Two of this book will
provide information about the struxcture, scoring, and
content of the AP Calculus Exam.
help you to make a study plan.
point you towards additional resources.
Part Three of this book will explore various strategies:
how to attack multiple choice questions
how to write a high-scoring free response answer
how to manage your time to maximize the number of
points available to you
Part Four of this book contains practice drills covering all
of the AB Calculus and BC Calculus concepts you will find
on the exams.
Part Five of this book contains practice tests.
You may choose to use some parts of this book over others, or
you may work through the entire book. This will depend on
your needs and how much time you have. Let’s now look how
to make this determination. HOW TO BEGIN
1. Take a Test
Before you can decide how to use this book, you need to
take a practice test. Doing so will give you insight into your
strengths and weaknesses, and the test will also help you
make an effective study plan. If you’re feeling test-phobic,
remind yourself that a practice test is a tool for diagnosing
yourself—it’s not how well you do that matters but how
you use information gleaned from your performance to
guide your preparation.
So, before you read further, take the AP Calculus AB
Diagnostic Test starting at this page of this book or take the
AP Calculus BC Diagnostic Test starting on this page. Be
sure to do so in one sitting, following the instructions that
appear before the test.
2. Check Your Answers
Using the answer key on this page (for Calculus AB) or this
page (for Calculus BC), count how many multiple choice
questions you got right and how many you missed. Don’t
worry about the explanations for now, and don’t worry
about why you missed questions. We’ll get to that soon.
3. Reflect on the Test
After you take your first test, respond to the following
questions:
How much time did you spend on the multiple choice questions?
How much time did you spend on each free response
question?
How many multiple choice questions did you miss?
Do you feel you had the knowledge to address the
subject matter of the essays?
Do you feel you wrote well organized, thoughtful
essays?
Circle the content areas that were most challenging for
you and draw a line through the ones in which you felt
confident/did well.
Functions, Graphs, and Limits
Differential Calculus
Integral Calculus
Polynomial Approximations and Series (for BC
Calculus Students)
Applications of Derivatives
Applications of Integrals
4. Read Part Two and Complete the Self-Evaluation
As discussed in the Goals section above, Part Two will
provide information on how the test is structured and
scored. It will also set out areas of content that are tested. As you read Part Two, re-evaluate your answers to the
questions above. At the end of Part Two, you will revisit
and refine the questions you answered above. You will then
be able to make a study plan, based on your needs and
time available, that will allow you to use this book most
effectively.
5. Engage with the Drills as Needed
Notice the word engage. You’ll get more out of this book if
you use it intentionally than if you read it passively,
hoping for an improved score through osmosis.
The drills are designed to give you the opportunity to
assess your mastery of calculus concepts through testappropriate questions.
6. Take Test 2 and Assess Your Performance
Once you feel you have developed the strategies you need
and gained the knowledge you lacked, you should take one
of the practice exams at the end of this book. You should
do so in one sitting, following the instructions at the
beginning of the test. When you are done, check your
answers to the multiple choice sections.
Once you have taken the test, reflect on what areas you
still need to work on, and revisit the drills in this book that
address those topics. Through this type of reflection and
engagement, you will continue to improve.
7. Keep Working
As you work through the drills, consider what additional
work you need to do and how you will change your strategic approach to different parts of the test.
If you do need more guidance, there are plenty of resources
available to you. Our Cracking the AP Calculus AB & BC
Exams guide gives you a comprehensive review of all the
calculus topics you need to know for the exam and offers 5
practice tests (3 for AB and 2 for BC). In addition, you can
go to the AP Central website for more information about
exam schedules and calculus concepts. AB Calculus Diagnostic Test
(Click here to download a PDF of Diagnostic Test) AP® Calculus AB Exam DO NOT OPEN THIS BOOKLET UNTIL YOU ARE TOLD TO
DO SO. Instructions
Section I of this examination contains 45 multiple-choice questions. Fill
in only the ovals for numbers 1 through 45 on your answer sheet.
CALCULATORS MAY NOT BE USED IN THIS PART OF THE
EXAMINATION.
Indicate all of your answers to the multiple-choice questions on the
answer sheet. No credit will be given for anything written in this exam
booklet, but you may use the booklet for notes or scratch work. After you have decided which of the suggested answers is best, completely fill
in the corresponding oval on the answer sheet. Give only one answer to
each question. If you change an answer, be sure that the previous mark
is erased completely. Here is a sample question and answer.
Sample Question
Chicago is a
(A) state
(B) city
(C) country
(D) continent
(E) village
Sample Answer Use your time effectively, working as quickly as you can without losing
accuracy. Do not spend too much time on any one question. Go on to
other questions and come back to the ones you have not answered if you
have time. It is not expected that everyone will know the answers to all
the multiple-choice questions.
About Guessing
Many candidates wonder whether or not to guess the answers to
questions about which they are not certain. Multiple choice scores are
based on the number of questions answered correctly. Points are not
deducted for incorrect answers, and no points are awarded for
unanswered questions. Because points are not deducted for incorrect
answers, you are encouraged to answer all multiple-choice questions. On
any questions you do not know the answer to, you should eliminate as
many choices as you can, and then select the best answer among the
remaining choices. CALCULUS AB
