How unit tests work

Focused on a single AP unit, between a single-topic quiz and the full diagnostic.
4 variations per unit — pick a fresh variation any time you retake.
Roughly 90 seconds per question — the same pacing as the AP exam.
You'll get a unit-level score, recommended topics to review, and a question-by-question explanation.
