[mzltest]

This will be my first SAS product. Exams will be completely free for any students and open to all exams. You will only pay for the customize exams or private exams.

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.
