K.A.
I put my son in summer school for two classes one year. He was probably between 10 and 12 yrs old. He didn't fail any classes, but he didn't take school serious enough. He was smart enough..just lazy and didn't like the work either. I told him it wasn't a punishment..I just wanted him to stay on top of some of the important classes. He did a math class and an english class. He actually liked it and did much better the following year in those classes but still doesn't take school as serious as I would like. When he went it was only a few hours a day so it wouldn't ruin your daughters summer. I do not remember the cost though. It wasn't free..I remember that. It may be cheaper than having a tutor though...something to look into. Call your daughters school and get some info on both.
