I agree with the others, ask around for a private tutor. We did Kumon and we were not impressed at all. When we were there it was a worksheet based program that we did at home! We were never actually at the place for more than 20 minutes a time. There was absolutely no progress at all after a couple of months. We went to a private tutor and we started seeing improvement pretty quickly. The one in town, it had a monopoly (no Sylvan close by), closed about 4 years after it opened.
