Auto-generated from all reviews of this business. For reference only.My 8-year-old daughter has been attending mental arithmetic classes for 2 months, and we are very happy with her progress. Before starting, she could only count on her fingers up to 10. Now, after just two months, she confidently and happily counts on the abacus up to 1000. She truly enjoys the lessons, and we can already see a big improvement in her math skills and confidence. Highly recommended!
We had clases during 6-8 month, for 12 year girl. She like it. Productive and high-quality lessons.

My son is 10 years old and he used to have significant difficulties with math at school. We started Abacus classes at your school, and we would like to share a positive review. Since beginning the program, he has learned to calculate much faster, and his coordination has improved significantly. He is now doing much better in mathematics, achieving good grades and showing real progress and confidence in the subject. Overall, we are very happy with the results and the learning experience. We highly recommend your Abacus school to other parents.
