How practice works
Use mixed practice or focus on a chapter. Multiple-choice and numeric responses receive objective feedback. Written, graph and code responses use an analytic self-review checklist; code is not compiled and graph work is not automatically graded.
Coverage and review
Formative original practice aligned to the preparation topic map. This is an incomplete preparation beta with provisional difficulty, written self-review and no official score prediction.
Original questions and lessons have independent AI review. Human academic approval, empirical difficulty calibration and measured score improvement are not established. Our examples and questions are not official assessment items. Read the full practice scope.
