01 / Overview
Overview
Medical and nursing students revise for QCM exams from printed banks that never say which topics are weak, so the product is one loop: practice a set, see the weak areas, retry them. It deliberately has no database. The question bank and class roster are seeded from the repository, and each student's progress lives in a signed, compressed cookie, which removes a cloud store of student data at the stated cost of syncing across devices.

Where it stands
Deployed at svaengyul.com behind sign-in: one class roster signs in with seeded accounts, and anyone can register a device-only account with a Telegram code. Progress stays on the device that made it, no question has instructor review yet, and credential rotation remains open before wider use.
