What one sitting is like

Any tests still owed open in your account automatically once enough new tests are published to fill the remainder of your pack, and each test's 12 months of access start on the day it opens.

Each test follows the exam College Board publishes for May 2027, section by section, as shown here. Like every AP test on this site, it ends in a report with an estimated AP score from 1 to 5.

Your report
Your report opens the moment you hand the test in: your score, a section-by-section breakdown, and anything still being scored, named and added as it arrives.
AI Tutor
Your AP Computer Science Principles test is over and your report is open: pick a mistake on your results page and the AI Tutor starts from there. It asks you the question and writes the steps out on the board, so you find where you went wrong rather than being handed the answer. The first 2 mistakes are free, for up to 10 minutes.

How it compares with the real AP Computer Science Principles exam

Adaptation

Not adaptive, like the real exam: everyone who sits a given test answers the same questions.

Interface and tools

  • Packs of 1, 5 or 10 full-length tests in the 2027 format
  • The tests you buy open in your account automatically once enough are published to fill your pack
  • Each test's 12 months of access start on the day it opens

Scoring and differences

Like every AP test here, each test ends in a report with an estimated AP score from 1 to 5, worked out with our estimated cut-offs because College Board publishes none. It is not a College Board score.

  • The 1–5 score is an estimate: College Board does not publish the composite needed for each score.

    Questions

    When do my AP Computer Science Principles tests open?

    Any tests still owed open in your account automatically once enough new tests are published to fill the remainder of your pack, and each test's 12 months of access start on the day it opens. Nothing needs to be done on your side: the tests appear in your account.

    Which tests will I get?

    New tests you do not already hold, in the order they are published, up to the 10 planned for AP Computer Science Principles. A pack is never filled with a test you already have.

    How many times can I take each AP Computer Science Principles practice test?

    Each test can be sat up to 2 times. If you close the tab in the middle of a sitting, your answers are saved and the same sitting resumes when you return.

    Is the score official?

    No. Like every AP test here, each test ends in a report with an estimated AP score from 1 to 5, worked out with our estimated cut-offs because College Board publishes none. It is not a College Board score.

    How long does access last?

    Published practice tests you buy stay available on your account for 12 months from the date of purchase. Tests sold before publication open automatically once enough new tests are published to fill the remainder of your pack; their 12 months of access start on the day they open. Nothing renews and nothing is charged again.

    Can I get a refund?

    Practice tests, question banks and AI Tutor time are digital content. You can ask for a refund of a digital product you have not used within 14 days of the payment date. A product counts as used once any practice test in the pack has been started, any question in a paid section of the question bank has been opened, or any second of AI Tutor time has been used; a used product is not refunded. If you are charged twice by mistake, contact us and the duplicate charge is refunded.
