The official AP study guide: the Course and Exam Description

The closest thing to an official AP study guide is the Course and Exam Description, or CED, for your subject. It’s free from College Board and lists every unit, what you need to know, the exam format and sample questions. Pair it with real released free-response questions and you’ve got the core of your study plan.

What’s in a Course and Exam Description

You’ll find it on your subject’s page on AP Central or AP Students. Use the current one, because some courses, like Psychology and Calculus AB, have been revised recently.

  • The units, in order, with the topics and skills for each one
  • How much of the exam each unit is worth
  • The exam format: number of questions, timing and weighting
  • Sample multiple-choice and free-response questions with scoring guidelines

Practice with real past questions

AP Central posts the free-response questions from the last three exams, with scoring guidelines, sample student answers and score distributions. Grade your own answers against the scoring guidelines. That’s the best way to see what readers look for.

Some older questions don’t fully match revised courses. AP Central marks those, so check the note on the page.

Use AP Classroom if you have it

Once you join your class in My AP, AP Classroom gives you AP Daily videos for every unit, plus progress checks your teacher can assign. You can rewatch the videos as often as you like, and search their transcripts for a topic.

Try the exam app before the day

Download Bluebook, sign in with your College Board account and pick Test Preview for your subject. Previews are untimed and don’t give a score, but they show you exactly how the exam screens, tools and calculator work.
