The assumption that an online test is automatically easier to cheat on than a paper one isn't entirely accurate — a few simple settings, available directly in the activity, meaningfully reduce the risk without requiring elaborate additional supervision.
Shuffling question and answer order
From Settings → Randomize Order, each student receives questions (and, on some types, answer choices) in a different sequence — "visual" copying from a neighbor becomes much harder when screens don't show the same sequence.
Per-question timer, not just a whole-test timer
A timer that limits time on each question individually, not just the whole test, reduces the time available for looking up an answer outside their own knowledge — the student has to respond quickly, from what they actually know.
Multiple versions of the same activity
For parallel classes or different groups, duplicate the activity and change the order or values (especially with the Math Generator, where exercises regenerate automatically) — you remove the risk of answers circulating from one group to another.
Quiz Live for synchronized supervision
When all students answer simultaneously, on the same question, with the teacher actively watching the class progress on the projected screen, the opportunity to consult hidden materials drops significantly compared to a self-paced individual test.
No digital measure completely eliminates the risk of cheating — same as with a paper test — but the combination of shuffled content, strict timing, and active supervision brings the risk down to a level comparable with a well-managed traditional assessment.
