Questions:
1. How old is your child?
2. this institution has a very good curriculum, I know they sell it all over the US to chinese schools - my daughter went to one of those here in VA where we live, they were not good enough for us BUT the curriculum/materials are very good; so we got them and we are using them at home; if you contact them - they may be able to give you a list of places that use this curriculum in your area and then attend a class as a guest and take it from there. (pls call them the website just show one level but their curriculum has over 6 levels.
