Hiya,
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
