Hello.
I want to massively override (in all my Moodle courses) the Moodle letter grades by the letter grades at the course level, or in other words, do what is shown in this post (check the option: override site defaults), but in a massive way, it can be done through from the database.
I have more than 1000 courses, and doing it manually in each course would be complicated.
I would appreciate the help.
