BI & BM · REVIEWED EDITION 2.4.0
MANDARIN · 华语
When on, BI and BM remain visible and the hold button is unnecessary. When off, use the main-screen hold button to reveal them temporarily.
Off by default. Confirm teaching in Mandarin, BI and BM before enabling each category. These controls show labels; they do not test pupils.
Editorial bands preserve earlier lesson groupings. They are not verified SK, SJK(C), Cambridge or American year-level equivalences.
Physical: hold the main-screen button to reveal BI and BM temporarily; release to hide them. Settings can keep both translations visible instead. Online: the teacher answer stays visible. Open Student Presentation and share only that window in Zoom. Reveal and navigation synchronise within the same origin and browser profile; this is not cross-device synchronisation.
The teacher view is private because you keep it off the shared screen. There is no sign-in access restriction. Vocabulary and source code are public. Students need no device during your lesson.
Wait for “Offline files ready”, then test without a connection. Progress stays on this device; clearing browser site data removes it. Export a backup before clearing data. No AI service, account, camera or microphone is required.
