What Our Students Say

Learning Abacus and Mental-Arithmetic became part of my life when I was 5 years old. Back then, the formulas were foreign to me. Through these years, I grasped the rationale behind these formulas. They were actually magical numbers to do calculations! I was amazed at knowing how an abacus could do multiplication and division of large as well as decimal numbers without using a calculator. When doing mental-arithmetic, the formulas would aid me too. Mr Lee has always been there for me. When I faced difficulties, he helped me overcome them. He taught me techniques, tricks and tips that could not be found in textbooks. He has made learning abacus fun and interesting. Learning Abacus and Mental-Arithmetic improves my memory. It also inculcates discipline and helps me focus in my study. If given the opportunity, I would like to guide other children. I am happy and grateful to master this international language.

I started learning at the age of 3 at 3G Abacus, all these years, the mental arithmetic has helped me to gain confidence, especially in situations where I have to think fast. It also helped me to get successful entry into NUS High. Your patience and passionate teaching was very beneficial to me, and I hope that it will continue to benefit me in the future. I want to thank you for teaching me all these years, and am very grateful for the experience of learning here. Thank you Mdm Chee

Adrian Bih – 12 YO

Children Student

I have started to pick up 3G Abacus since I was 5 years old.  At first, I was afraid that the sums were too complex and confusing.  However, I was surprised that I was able to grasp the formulas within a month!  Instantly, I developed a strong passion for Abacus and Mental-Arithmetic and doing practices incessantly every day. When I went into primary school, I realized that I was already one step ahead of the others as I knew all the multiplication and division sums.  In addition, it allowed me to do my workings quicker than the rest.  Hence, I managed to ace in my Mathematics examinations and would learn new Mathematics skills faster than my peers. During my learning process in 3G Abacus, I certainly faced setbacks.  Due to the massive amount of homework and revision for examinations, I only had little time to practice, especially at Primary 6.  In addition, my previous instructor, Mr. Lee, had fallen ill.  As such, I had to travel further to Jurong to be coached by Mdm. Chee and needed to adapt with the sudden changes quickly.  Luckily, I managed to persist and overcome these challenges. I managed to clinch Abacus Grade 1 and Mental Super Degree this year.  In addition, I was the second person to achieve the Triple Crown Award.  At that point of time, I was overwhelmed with gratitude to those who had spent relentless hours to coach me. Through this learning, I did not only learn mathematics sums, but also crucial life skills to prepare for my life-long journey – better concentration and disciplined.  Thank you 3G Abacus!

He started learning 3G Abacus in primary one and after 2 years, he is currently undertaking the post advanced courses with 3G Abacus.Wei Ren shows strong interest in mathematics and that was the driving factor for him to take up the Abacus class. He has now been almost two and a half years learning Abacus. The course indeed helps him to speed up the mathematic learning and improves his mathematic results, making him more enthusiastic in studying mathematics. Thank you 3G Abacus for providing various chances to Wei Ren to participate in various International Competition in Singapore and overseas, where he clinched 1st and 2nd prize. These competitions helped him to realized his potential in the mental arithmetic aspects. It is certainly a great and meaningful experience to him, and obtaining a gold award in the 2017 Malaysia International Mental Arithmetic Competition is a great encouragement for him to excel further!
