Greetings to all!
I have a problem. I coordinate a training course in my orgnaization, but it has charged all the users data since the beggining of the usage of the moodle. In this moment, everybody is required to retake the course and recertificate through the quiz charged in the course. This quiz has a limit of 5 attempts and a lot of users run over attemtps in the past and now they can't retake the quiz. Is there any way to remove all the old grades, adding some filters to the search so I can erase the old registers, or at least a filter to search by username? I have more then 15 thousand attempts, so it is quite difficult to look one by one. I'm using Moodle 2.1, expecting to migrate to 3.7 soon.
