# AP Computer Science

## About the Test

Check out the description from [College Board](https://apstudent.collegeboard.org/apcourse/ap-computer-science-a) including the [description of the test](https://apstudent.collegeboard.org/apcourse/ap-computer-science-a/about-the-exam). For the technical folks (it'll be more useful later in the year), [this is also a handy document](https://secure-media.collegeboard.org/digitalServices/pdf/ap/ap-computer-science-a-java-subset.pdf) about the features of Java that the test uses. As of the time of this writing, there are two sections:

1. Multiple choice: 40 questions, 90 minutes, 50% of your score
2. Free response: 4 questions, 90 minutes, 50% of your score
