On harder concepts, I feel like when the user gets a question wrong, it sets back your progress by too large an amount. I am doing these problems on simplifying Exponents (and I know the concept well) but I'm doing the problems in my head and make an occasional arithmetic mistake.
The mistakes I'm making aren't because I don't get the concept, but because I made a small error along the way.
