Hi, I'm Ai Ling Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths.
I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way.

If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
