Both the AP Calculus AB and BC tests include a section of six *free response (FR)* questions. These questions differ in many ways from standard multiple choice problems. In this post, we’ll talk about a few tips to help you conquer the AP Calculus free response questions.

## Tip #1: Don’t Panic (and Be Prepared)

I’m sure that you’ve seen free response questions before. By definition, any problem that does not provide a set of answer choices to select your response from is a free response question. That typically covers the majority of quizzes and tests in high school.

So there’s no need to panic, as long as you know your material.

Make sure that you’ve prepared for the AP Calculus exam well in advance.

## Tip #2: Read Carefully

This should go without saying, but *read every question very carefully*.

Often mistakes arise when the student misreads or misinterprets a question. Make sure you know:

- What is the question asking?
**(Goal)** - What do I know from reading the question statement?
**(Givens)**

## Tip #3: Show Your Work

This is probably the most important tip for achieving a high score on the FR section.

The graders are not just looking for a final answer. Instead, you **must** show every step of your work in a logical progression toward the answer.

This means that if you have invented some wacky way to do an integral in your head for example, but you have no clue how to explain what you did on paper, then you won’t get a lot of points in the FR section.

### What About Calculators?

Calculators are permitted on some problems in the FR section. But you must explain how you used the calculator functions (except for routine arithmetic).

For example, suppose there is a question asking you to find the area between two curves. You must first show the integral that properly computes this area.

Only then can you plug it into your calculator and find the answer. On your test paper, you would write down something like this:

“I used numerical integration on my calculator to evaluate the integral.”

Then jot down the answer, and now you’ll be sure to get full credit!

Here are those tips one more time.

- Read Carefully
- Show Your Work
