Be clear about one thing first: no browser plugin can stop a determined cheater. A second phone or a helper in the room defeats any software. What you can do is make cheating inconvenient and make honest practice the easy path.
Fullscreen lockdown is part of Exam Mode, which is included in Turgor Pro.
What fullscreen mode does
- Opens the exam in fullscreen
- Warns the student when they leave it
- Records how many times it happened (check the plugin for what it logs)
Together this tells you who switched windows, and it reminds students that the exam is serious.
What it doesn’t do
- Detect a second device
- Identify who is sitting the exam
- Work identically on every phone browser
Does cheating matter for mock tests?
It depends on your purpose.
- Practice tests: a student who cheats only hurts themselves. Keep the rules light.
- Ranked test series or scholarships: integrity matters. Use stricter settings.
- Admission or paid certification: consider an in-person or proctored setting.
Practical measures that work
- Randomise question and option order so answers cannot be shared by position.
- Use a question bank larger than the test, so each student gets a different paper.
- Set a strict timer so there is no time to look things up.
- Show warnings clearly before the exam starts.
- Review the violation log and follow up on repeat offenders.
- Rank by percentile within a cohort, not only by raw score.
Fairness on phones
Fullscreen behaves differently on mobile browsers. Test it on common devices and decide whether leaving fullscreen is a warning or a failed attempt. Do not punish students for a notification popup.
Tell students in advance
Put the rules on the instruction page: what is logged, what happens after a warning, and what the consequences are.
