AP Calculus BC Multiple-Choice Questions Strategies
The AP Calculus BC Multiple-Choice Questions Strategies
There are 45 multiple-choice questions for the AP Calculus BC exam. These questions are divided into Section I-Part A, which consists of 30 questions for which the use of a calculator is not permitted; and Section IPart B with 15 questions, for which the use of a graphing calculator is allowed. The multiple-choice questions account for 50% of the grade for the whole test.
Do the easy questions first because all multiple-choice questions are worth the same amount of credit. You have 60 minutes for the 30 questions in Section I-Part A and 45 minutes for the 15 questions in Section I–Part B. Do not linger on any one question. Time yourself accordingly.
There is no partial credit for multiple-choice questions, and you do not need to show work to receive credit for the correct answer.
Read the question carefully. If there is a graph or a chart, look at it carefully. For example, be sure to know if the given graph is that of f(x)or f′ (x). Pay attention to the scale of the x and y axes, and the unit of measurement.
Never leave a question blank since there is no penalty for incorrect answers.
If a question involves finding the derivative of a function, you must first find the derivative, and then see if you need to do additional work to get the final answer to the question. For example, if a question asks for an equation of the tangent line to a curve at a given point, you must first find the derivative, evaluate it at the given point (which gives you the slope of the line), and then proceed to find an equation of the tangent line. For some questions, finding the derivative of a given function (or sometimes, the antiderivative), is only the first step to solving the problem. It is not the final answer to the question. You might need to do more work to get the final answer.
Sometimes, it is easier to work backward by trying each of the given choices as the final answer. Often, you will be able to eliminate some of the given choices quickly.
If a question involves decimal numbers, do not round until the final answer, and at that point, the final answer is usually rounded to 3 decimal places. Look at the number of decimal places of the answers in the given choices.
Trust your instincts. Usually your first approach to solving a problem is the correct one
