Would anyone be interested in working on a new Availability condition, based on the quiz sectional scoring? (Quiz sectional scoring was added in Moodle 4.4 in MDL-74610.)
The idea would be an availability condition which allows (or prevents) access to another activity, based on whether the score for a particular question in a particular quiz is higher or lower than a particular level.
This is a bit like this other plugin the some of us created at the DevCamp a few years ago: Restriction by single quiz question. Unfortunately that got broken by changes in the core question bank (adding question versions), and it has never been repaired. I guess an alternative, or additional challenge, might be to try to repair it.
