Where Svaeng-Yul stands

Medical portal

Practise 1,750 questions across 5 subjects, and see your score and the answer key when you finish.

Your own questions

Write private question sets and practise them: up to 6 sets and 24 questions in one browser.

Accounts

Sign in with a class account, or create your own with a code from the Telegram bot. An account you create lives in the browser that created it, for 30 days.

Study hints

Written by a self-hosted model when it answers, and a fixed study prompt when it does not. Model hints are checked for wording that gives the answer away, and can still be wrong.

Your progress

Saved in this browser for 30 days after it last changed: your history, XP, badges, saved posts and question sets.

Deleting your data

Profile, then Settings, then “Delete data on this device”. The privacy page lists what that removes.

Explanations

0 of 1,750 questions show a written explanation. Until a question is reviewed, the answer screen says so instead of explaining it. Check answers against your course materials.

• Sync between devices. Progress stays in the browser you study in. Another phone, or a cleared browser, starts empty.
• Pass reports to a person. “Report issue” saves your report on this device, but no reviewer can read reports yet. To reach a person, write to chnailab@gmail.com.
• Rank you against classmates. The leaderboard shows your own row; every other row is a labelled sample.
• Reset a password. An account created with Telegram exists only in its browser, so a forgotten password means creating a new account there.
• Open the other portals. Software Engineering, Cybersecurity, Computer Science, Data Science, AI Engineering are listed as under maintenance and cannot be opened.
• Work in Khmer. The app is in English. Khmer text in the questions displays in a Khmer font.
• Take payments. Svaeng-Yul is free, and there is no way to pay.

• Hosting: Vercel. This page was served from Washington, D.C., United States.
• No database. An account you create and your progress are signed cookies in your browser. The server reads them to answer each request and stores nothing; a running server can hold a copy in memory until it restarts.
• Updates are deployed by hand after the automated checks pass, so the site can change without notice during the preview.
• No uptime guarantee and no status monitor yet. If something is broken, write to chnailab@gmail.com.

No company is registered behind Svaeng-Yul. For help, privacy and deletion questions, a wrong answer, or a security problem, write to chnailab@gmail.com. The contact page says what to include.
