An offline-first revision app (PWA) for STAT 312 — Stochastic Processes at Qatar University (Fall 2026): a live semester timeline, per-stage revision hubs, spaced-repetition flashcards, an interactive practice-quiz engine built from the Fall 2026 sample quizzes, a searchable formula sheet, and an FAQ. Installable on phones, works fully offline — no backend, no accounts, all progress stored in the browser.
