Difficulty Modes?

What if quizzes had different modes with different difficulties? Because I see a lot people making several different versions of the same quiz, just giving more time or adding extra hints.

The quiztaker could select if they want to play on easy or hard mode and the quizmaker wouldn't need to make another quiz.

Of course, this might be too complicated and wouldn't really fit into the points system.

Anyways, I would love to hear your thoughts about this in the comments!
