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.
