Kumon has a good education circulate and it has a good timing for children. I think it's bad to turn to another education centre.I think your two childrens are very high level, isn't it? I think they can finished to final level.
我雖然只係P.6, 但我有小小意見. 我由4 years old 就start to learn KUMON MATHEMATICS, 雖然係升o左好多個grade, 但進步不大, 所以無學one period, 後來學返, but it 不但cannot help me, 仲成為o左我o既負累, maths成績愈來愈差, 最後都無學lu!!!
希望我小小o既意見can help you la!!
