Hi YoonJu, I could definitely tell this is something that you care about and want to develop a solution for. Tutoring is very expensive and it seems as the demand is only getting higher as competition in schools get more fierce. That being said, I felt like this is a venture that exists already in some form and it was not a unique implementation. Getting schools to also pay for tutoring services seems very counter intuitive, since the teachers at the school are the ones that are supposed to be doing the teaching. Something I found that works very well in our school is peer tutoring (more academic students tutoring less academic students) or having high school students volunteer to tutor younger grades. Perhaps your idea could be developed further to help encourage this type of peer tutoring and create a more of a social venture!
