How to allow a particular user to take quiz very next day in drupal I have gone through so many question asked here but not find exact answer. The main problem I have faced is to create a quiz using 7.x-4.0-rc2, I made some user who can take quiz. One user can take quiz only once, but I need that particular user can take quiz again very next day (After 12AM).
I would suggest to make use of rules: 


Create user role (by hand) which always access to quiz let say QUIZER
On Event "I want to enter Quiz"
Look up Time Last entered date from current olr
Check if allowed to go on
Add role quizer to current user
On event "I'm stopping the Quiz"
Remove role quizer from current user
Save Time last entered Quiz in user profile
