Great, as a first one. Glad to see that the level is increasing a bit through the quizzes. However, I think that it would have been great to keep the same timer. I think that's currently way too easy. I'm not fast nor good at maths and I finished it in just more than one minute. I think you could easily decrease the timer by 1:30-2 minutes.
I was worried that the difficulty would be way too high for a #2 so I compensated it with a generous timer. Maybe you're right and I could bring the time to 2 minutes like the 1st quiz. I'll wait for a few more takes and see the scores/feedbacks too.
I also didn't go through 27, and it's because I misread the clue at 0 as squaring rather than cubing. In my defense, the font is really small even on my laptop. By coincidence, that ends up skipping just the 27 and going straight to 9.
Maybe change the clue under 0 to ^3 instead of the superscript.

I want to avoid the (^3) form as much as possible because it would make the text not fit in the boxes :)
