Hello, im trying to understand how the gradebook works (which querys use etc)
If someone can helpme please do it
Have a nice day.
In the developer documentation if you search Gradebook you get a lot of links http://docs.moodle.org/dev/index.php?title=Special%3ASearch&search=gradebook&go=Go relating to the Gradebook. I don't know if they help. Make sure you look at gradebook 2 from 2010 onwards rather than earlier ones. If you just want a basic overview without the techie stuff then look at our user documentation Gradebook
There is quite a bit of documentation in the Moodle docs. I suggest starting there and then trying a slightly more specific question! What exactly do you need to know how to do?
