I'm using moodle 3.6.4
I have a topics based course set up. Each topic has an "assignment", Not like the normal assignment found on moodle, instead each "assignment" consists of a number of quizzes. I created a module 1 category and an assignment category which contains all the quizzes. Students need to gain a 50% or higher in order to pass each quiz but in order to gain a passing mark for the assignment every quiz within a module needs to be passed. Currently i have letters set up "C" as a pass for 50% or higher and "NYC" for anything below, this makes the mark for the assignment category a pass even if a quiz is failed.
I'm not really sure where to look in order to accomplish this so any help would be appreciated.
I have included a screenshot of the gradebook set up, please let know if you need any other information.
If you're wondering why the assignment weight is 50.0, there is an exam which also counts for 50.0
