Hi.

I am looking to provide some online exams (forms) on a website I am building.
However I want to lower the chance of individuals cheating and therefore want to provide different exams to different users.

I would like each registered user when logged in to view a different exam (form) on the exam page.

I was thinking of simply giving different users different user groups, where each user group has permission to view one of the exams on the page, thus different users should be able to access only one exam version.

Is their anyway to do this automatically and automatically assign users a random (out of a predefined list) user group upon registration?

Much thanks in advance!
