If you gave a quiz and it is not showing up in the gradebook, chances are you left the quiz's point value at its default setting of 0, give it a point value in the quiz settings and it will show up in the gradebook.
Finally, the current moodle gradebook is rather primitive, it just shows points. We're building a new one, which handles grade weighting, catagorization, dropping grades, curving, etc. It is in CVS/contrib in the 'gradebook_cdc' folder, or you can read about it and download it here.
Follow the readme instructions for installation, and of course back up your site and database first.
Thanks for replying.
I followed your suggestion and downloaded the files from your site. How many files should it contain? Currently it has two 'grades' files but no 'grade' files
your instructions suggest it needs both?
"To install the code as the standard gradebook, just replace the standard course/grades.php and course/grade.php with these versions, now the grades link will point to the new gradebook."
