Every day, when I go to school, out teacher tells us to do classcard battle. Classcard battle is a just quick 4 minutes battle solving math problems (Also there is English, but it's all from the national curriculum!), and if we get to do the first place, for the math, the class will get 30 million in Korean money, and will get 15 million monies for English. That is why our teacher wants us to be the first place, especially math to buy us something. However, we can only do 3 people in minimum and the less people, the higher percentage that we can get to the first place.
However, our class was not that good at math except for me. I was almost the world's record to solve 150 questions in 4 minutes which was all correct. (Actually, it was all just calculating the expression of natural numbers and fraction's plus and minus, but still, it was complicated.) So, our teacher used like all of the ways and found out that he can just pick people that are good at it and let them do it. Our teacher first let all of the class to do it, and choose half, then half, half, half and 3 people was chosen. Me, Logan and Jun Yeong.
Eventually, our class did both first place and got to buy a pencil case and sharp for each person.
It was very good choice to practice it every day!
(In fact, the challenge is over so don't try it or your arm's gonna break!)
