“I have done several online courses with AOPs and mymathcounts. I felt that your course was the best of them all. I liked that your solutions were very smart and clear. It made me think. I also liked the fact that you gave multiple explanations to solve the same problem. I am looking forward to the next Module. I would give 5 stars.”

“Geometry Tools is a great course if you want to learn more about Geometry. Professor Po Shen Loh teaches a lot of great tricks that you can use to solve some difficult problems. I have learned a lot of tricks and tips, including how to square a number, that ends in 5, in just a few seconds. After I completed only 15% of the course, I learned a lot of material that I had not learned in school. I improved greatly on most of my geometry tests. I am very happy about my improvement in Geometry and plan to take the Module 3: Combinatorics Tools and Module 4: Algebra Tools. Thank you, Professor Po Shen Loh, for taking your time to make videos to try to help younger people, and I hope you make more courses! ”

“This is a very fun (but hard!) course. I like how the problems are given to introduce new concepts and the solutions are very clear, and how even though there's a lot of stuff covered, it's presented in only a few problems.”

“Best learning system ever! I love how we do only a few questions at a time and figure it out in different ways instead of rushing everything up. I got some questions wrong, but that's how I learn! Keep up the hard work!”

“This is the best maths course I ever had! Prof Loh gives us challenges for us to solve and then he explains it clearly himself. The weekly exams help, too. This is indeed the best maths course.”
