What exams does Cognify cover?

Cognify covers AP Psychology, Digital SAT, AP Biology, and AP Statistics with practice tests, rubric-graded FRQs, and score prediction.

How does Cognify compare to Khan Academy?

Cognify focuses on exam-format practice with AI grading and score prediction. Khan Academy provides broad video instruction. Cognify is purpose-built for AP and SAT exam day performance.

How does Cognify compare to UWorld and Princeton Review?

UWorld and Princeton Review rely on static question banks that students exhaust after a few sessions. Cognify generates fresh questions on demand against the official College Board exam blueprint, so every practice test is unique. FRQs are graded point-by-point against AP rubrics with specific feedback on what you earned and missed.

How accurate is the AP score prediction?

Cognify maps your percentage correct to the public AP composite scoring buckets (1-5) using historical score distributions. The prediction improves as you take more practice tests. For the Digital SAT, scores map to the 400-1600 scale using official section score conversion tables.

Does Cognify cover AP FRQ practice?

Yes. Cognify provides rubric-graded FRQ practice for AP Psychology, AP Biology, and AP Statistics. Each response is scored criterion by criterion against the official AP rubric with specific written feedback explaining what you earned, what you missed, and how to improve.
