Manipulable 3D solids, live matrix editors, step-checked math — not another scanned PDF.
An IRT-based ability estimate shown as a practice range, labelled as practice — never an overclaimed prediction.
Parametric generators mean no memorized question banks — every attempt is a fresh, real item.
PPP-adjusted so the price is fair whether you're prepping from Lagos, Lima, or Munich.
