Guruscool abacus program has been a great investment for my child's education. The instructors are dedicated and have a deep understanding of abacus techniques. The progress my child has made is remarkable. The website is informative and easy to navigate. I highly recommend Guruscool abacus to any parent looking to enhance their child's math skills.
