The school thing is cool and all, but seriously even if they are simple math questions at begin its a feature that makes it not good imo, maybe if it was a automated feature something like this, a student answer the questions where it has a % of answering correctly and as we use books it would get a higher %, in a way it would make things easier and less rewarding to good math players, but it would make the game more acessible since not everyone is good at math even through like i said they are all simple questions till D+ (the rank ive achieved)
