Inside the AP Calculus AB Exam
Before you plunge into studying for the AP Calculus AB exam, let's take a step back and look at the big picture, What's the AP Calculus AB exam all about? How can I prepare for it? How's it scored? This chapter and the next will answer these questions and more.
What is the Advanced Placement (AP) Program?
Through the Advanced Placement Program, you can take college-level courses while you are in high school. Based on your grade on an AP Exam, colleges and universities can grant you placement or college credit or both.
In addition to getting a head start on your college coursework, you can improve your chances of acceptance to competitive schools since colleges know that AP students are better prepared for the demands of college courses. There's also the money you can save on tuition if you receive credit!
About the AP Calculus AB Exam
The AP Calculus AB exam is administered in May by the College Board's AP Services. The exam is 3 hours and 15 minutes long, so developing your stamina is very important. The exam consists of two equally weighted sections: Section I, Multiple-Choice, and Section II, Free-Response.
Section I -- Multiple-Choice
There are 45 multiple choice questions, This section is split into two parts: part A consists of 28 questions with no calculator allowed (55 minute time limit) and part B consists of 17 questions for which a calculator is required (50 minute time limit). Each multiple choice question is worth 1 point.
Section II -- Free-Response
The second section of the examination consists of 6 free-response questions worth 9 points each. Part A consists of 3 questions for which a calculator is required (45 minutes). Part B consists of 3 questions for which calculators may be not be used (45 minutes). During Part B, you may go back to the first three questions in Part A if you have time, but you will not be permitted to use your calculator.
What's the AB Stand for?
There are two AP Calculus exams and the AB distinguishes this exam from the AP Calculus BC exam. The AB exam covers one semester of college-level calculus, whereas the BC exam covers a full year of college calculus, although individual colleges may differ in their course offerings and placement/credit policies. You may take only one of the two exams in any given year.
Scoring
The AP Calculus exam is scored on a scale of 1 to 5, with 5 being the highest grade. The scores are defined as follows:
5 Extremely well qualified
4 Well qualified
3 Qualified
2 Possibly qualified
1 No recommendation
In 2000, the average grade of the 137,276 candidates who took the AB test was 3.03. Typically, to obtain a score of 3 or higher, you need to answer about 50 percent of the multiple choice section correctly, and do acceptable work on the free-response section. Remember that you can miss questions and still get a perfect 5 score.
Raw scores are calculated in points. The multiple-choice section of the AP Calculus exam is worth the same number of points as the free-response section. There is a 1.2 weighting factor used so that the multiple-choice and free-response sections of the exam have equal weight. Each section is worth 54 points, for a total of 108 points.
It would not be correct to say that the AP examination is graded on a curve. How other students do on the same exam will not affect your score. However, some multiple-choice questions are used from one year to the next to allow for a calibration of the scores so that a 4 one year reflects the same statistical strength of performance. For this reason, the cut-offs for each score level do not stay constant from year to year.
Wrong-Answer Penalty
For multiple choice questions, there is a penalty for incorrect answers as opposed to simply leaving answers blank. This is sometimes called a guessing penalty, but it is really a wrong answer penalty. If you guess fight, you're in great shape!
Here's how the scoring works: You receive 1 point for a correct answer, 0 points for no answer, and -1/4 point for a wrong answer. For example, getting 30 correct and 15 wrong would give you a score of 30-(15x1/4) = 26.25. We'll talk more about guessing on the AP Calculus AB multiple-choice section in the next chapter, Taking AP Calculus AB -- Strategies for Success.
What You Need to Bring
* Two calculators (see below) and batteries
* Photo I.D. (driver's license, school I.D., or a valid passport are acceptable)
* Your secondary school code number (see your Guidance Counselor or AP Coordinator)
* Your Social Security number
* Several sharpened No. 2 pencils
* Pencil sharpener
* Eraser
* A watch (in case your exam room doesn't have a clock you can see easily. You need to be able to pace yourself during this long test!)
What NOT to Bring
* DON'T bring scratch paper. You'll make your notes in the test booklet in the spaces provided.
* Don't bring books, compasses, correction fluid, dictionaries, highlighters, notes, or rulers.
* Don't bring beepers or cellular phones, or watches that have beepers or alarms.
* Don't bring food or drinks.
* Don't even wear a T-shirt with math of any kind on it!
Calculators
You can only bring two calculators, both of which must be approved types. To be an approved calculator, it should be able to:
* Produce the graph of a function within an arbitrary viewing window.
* Find the zeros of a function.
* Compute the derivative of a function numerically.
* Compute definite integrals numerically.
You can't use a calculator with a QWERTY keypad, because it makes it too easy to type text (such as test questions) into the calculator.
How Are Exams Graded?
The multiple-choice section of the exam is graded by computer. The free-response booklets are graded by faculty consultants. These are college professors and AP teachers who are specially trained to assess the questions. Usually about six faculty consultants review each free-response booklet.
How Do I Get My Grade?
AP Grade Reports are sent in July to each student's home, high school, and any colleges designated by the student. Students may designate the colleges they would like to receive their grade on the answer sheet at the time of the test. Students may also contact AP Services to forward their grade to other colleges after the exam, or to cancel or withhold a grade.
AP Grades by Phone
AP Grades by phone are available for $13 a call beginning in early July. A touch-tone phone is needed. The toll-free number is (888) 308-0013.
Registration
To register for the AP Calculus AB exam, contact your school guidance counselor or AP Coordinator. If your school does not administer the exam, contact AP Services for a listing of schools in your area that do.
Fees
The fee for each AP Exam is $77. The College Board offers a $22 credit to qualified students with acute financial need. A portion of the exam fee may be refunded if a student does not take the test. There is a $20 late fee for late exam orders. Check with AP Services for applicable deadlines.
Additional Resources
The College Board offers a number of publications about the Advanced Placement Program, including: Advanced Placement Program Course Description -- Calculus, A Guide to the Advanced Placement Program, and the AP Bulletin for Students and Parents.
