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.

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.
