This might be a stupid question but I have tried a couple of searches. The module quizzes have a label of ‘beginner’, suggest that the quiz could be made a harder. Is there a setting I can use to up the difficulty? Retaking the quiz keeps the same difficulty but changes on average one question. If I score 100% then I need to retake the whole quiz several time to get the benefit of a few new questions.
The difficulty can’t be changed.
The difficulty tag is mostly used in search results as far as I can tell, but I’m sure it has other internal uses too.
The quizzes are a useful learning tool and aren’t meant to be difficult, rather meant to cement what you’ve learned. If you’re interested, take a look at ‘Learning How to Learn’ from Coursera, it’s free.
The best thing you can do is set your own questions and test yourself. If that’s not possible, try QuizzLabs
