Two timers begin when you start: total elapsed time and active-work time. The active-work timer pauses when you switch tabs, minimize this page, or move to another app, and resumes when you return. Your work is saved in this browser; nothing is submitted automatically.

Work independently. Disable Grammarly, automatic spelling/grammar suggestions, AI tools, and writing assistants before starting. Mistakes are expected: this workshop assesses your ability to diagnose and construct English sentences yourself.
