Then I suggest making this as a survey rather then exam.As other members figured out - no protection.But once your started implenting the protection it's not longer broswer-side completable.You need process filtering,screenshoting,phone that used as 2nd camera and supervisioning utility(like OMS - https://oms.pintia.cn/ ),so that's a lot of effort needed.

But a survey system is better.If you want to use ot for education,just add some real-time updating in browser and mobile-friendly polls.I believe it's a easy job for you using something like websockets,or at the worst,periodly ajax refreshing.

Thank you for your support and valuable insights.

This open-source app just serves the only purpose, taking MCQ exams, unlimited and without any restricted feature. I have created replace google form for examination. My friend is taking an exam using google form and have a hard time doing that. I am making to help a lot of friends who just need enough to take a couple of exams and that's it. The current solutions are shady and they don't have any control over their data.
And I thought it will be a good project for me if it solves any problems.
