About the Exam

Important Update

AP Chemistry Exams will be offered on paper in early May and as a digital exam in late May and early June.

All versions of the exam will cover the full scope of course content, giving students the opportunity to qualify for college credit and placement. On the digital exam, students will answer free-response questions with a keyboard, rather than by hand. Students taking digital exams will not be asked to draw or graph as part of their response—rather, these skills will be assessed with questions about given diagrams or other stimuli. The digital exam app will include any symbols students would need to type their responses. No handwritten or photographed work will be accepted.

There are differences between the paper and digital versions of some 2021 AP Exams, and those variations differ by course. The information below applies to AP Chemistry only. View a summary of all 2021 AP Exam formats.

Note on 2021 Exams

There are differences between the paper and digital versions of some 2021 AP Exams, and those variations differ by course. The information below applies to AP Chemistry only. View a summary of all 2021 AP Exam formats.

The digital AP Chemistry exam will take the same amount of time as the paper exam, but will include:

  • More multiple-choice questions than the paper exam.
  • Fewer free-response questions than the paper exam. 

Free-response questions will consist of familiar tasks that could appear on a traditional AP Exam, but they will be answerable with a regular computer keyboard and won’t require drawing or graphing. The digital exam will include any symbols you would need to type your responses. All responses must be typed directly into the exam app. No handwritten or photographed work will be accepted.

In the multiple-choice section (where calculators aren’t allowed on the paper exam), the digital exam won’t include questions where you could benefit from using calculators.

You will be able to practice multiple-choice and free-response questions within the 2021 digital exam app, available in early April.
