Proven, not asserted
Every code-bearing question is executed at build time against a pinned Qiskit 2.x stack. Correct answers are proven, distractors are disproven — and the execution proof ships with the question.
Guided by the official syllabus
The eight official exam sections, their weights, and IBM's own recommended resources drive everything: study path, drills, and a faithful 68-question / 90-minute mock exam with per-section remediation.

Fully static site — no accounts, no backend, no cookies. The site counts anonymous, cookie-free page views and a few anonymous usage events (e.g. a quiz started or finished, with a coarse score range) via Umami — nothing tied to you. Your progress, mastery, and mock-exam history live in your browser and are yours to export. Anki decks and the e-book work offline.
