I have been going to Kumon for 90 months now. I started at age 2 1/2 and I am going to turn ten in three months.In reading I have passed 22 levels and I am on the second last level. In math I have completed 14 levels, and I have 7 levels to go (including X).Reading ends at L and I am at K. Math ends at X and I am at I. In level X you can choose whichever branch of math you want. It is after the level O. Each level has 400 worksheets.
