CasperPractice

AI-coached CASPer practice questions and full mock tests

Realistic question bank and full mock tests

Work through hundreds of typed, video and media-based scenarios, or take complete simulations that reproduce the CASPer sections, question order and per-question time limits.

Purpose-built AI scorer

Answers are graded by a model calibrated on a large set of real CASPer responses, returning a quartile estimate rather than vague encouragement, plus sentence-level notes on what weakened the answer.

Instant answer rewrite

After each attempt you get a stronger version of your own response, showing how to hold competing perspectives and land on a clear position without sounding rehearsed.

Competency coverage tracking

Attempts are mapped to the competencies CASPer measures, so you can see whether ethics, communication or collaboration is dragging your average down and drill the weakest one.
