Gradebook

I see it easy for an Admin to view grades from all courses completed by students:

1. Go into any of the courses
2. Administration block->Grades
3. Overview report (tab or dropdown)
4. Choose the student for which you wish to view a list of course grades

Having Moodle automatically calculate the final certification result is a different matter and would require some behind the scenes actions. We've used the cron.php program extensively to accomplish essentially the same thing for pre-registration of first-year students, questionnaires, placement tests, etc. They can't pick their registration date until everything has been completed which is merely a program that checks to see that all the grades are in and are satisfactory.
