Does Canvas know when you switch tabs?
Try it right now. Switch to another tab or window and come back — the counter below ticks up using the exact browser event Canvas's quiz log records. Nothing leaves your browser.
Switch to another tab or window and come back. Each switch you just made would appear in a Canvas quiz log as a “Stopped viewing the quiz” event, timestamped to the second — the trail instructors actually review.
What just happened
Every modern browser exposes a Page Visibility API that fires an event the moment a tab is hidden or shown. Canvas listens for that event during a Classic Quiz and writes it into the quiz log as a “Stopped viewing the Canvas quiz-taking page” entry, followed by “Resumed” when you come back. This test uses the identical event — so the number above is, quite literally, what your instructor would see.
One or two switches rarely matter. A timed quiz with a dozen of them, each lining up with a correct answer, is the pattern that gets a log pulled and reviewed. See exactly how it reads in the quiz log simulator.
The fix is to never leave the page
You can't un-flag a tab switch, so the only reliable move is to not create one. That's the entire idea behind the CheatGPT extension: it reads the question and answers it inside the quiz page, so there is no second tab to open and nothing for the log to record. Your timing stays natural and your attempt looks completely ordinary.
