Google Form Quiz with 10-Minute Countdown Timer (Apps Script Add-On)

Turn any Google Form into a timed quiz without risky auto-submissions. This lightweight Apps Script displays a visible countdown and, on zero, freezes inputs and prompts a manual submit. Perfect for schools, HR screens, and cert quizzes that require students to intentionally press “Submit.”

Key Features of Google Forms Quiz Timer

• Visible 10-Minute Countdown
  Fixed, responsive timer (changeable to 5/15/30+).

• Manual Submit by Design
  On timeout, the script disables further edits, shows a Time’s Up banner, and guides users to the native Submit button. No forced submission.

• Start Button / Auto-Start (Optional)
  Let users start when ready or begin on load.

• Refresh/Back Protection
  Timer state persists to block time-cheating via refresh.

• Native Stack Only
  Google Forms + Apps Script. No extensions, no paid APIs.

• Clean UI
  Minimal, unobtrusive, mobile-friendly.
