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. I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)

Approved Calculator Models for O-Level Maths by Ministry of Education Singapore

Last week, I was sharing with my O-Level E-Maths students on the calculation of mean and standard deviation by using the calculator. Almost everyone is using the Casio 95 SG Plus or similar model.

There was a student who used Sharp model which I wasn't so familiar with initially. But we figured out the usage for the calculation anyway.

I decided to check if the Sharp model calculator is approved for O-Level.

Here's the list of approved calculators for O-Level Maths, check and ensure your calculator is allowable. Otherwise, buy a new one now.

  • Quadratic Equations
  • Partial Fractions
  • Factor – Remainder Theorem
  • Modulus Function
  • Coordinate Geometry

To help students to revise on some of the essential concepts, I have prepared a short list of questions on Expansion, Solving Quadratic Equations & Understanding Quadratic GraphIt will only take students 10 - 15 minutes to complete and the step-by-step solutions (+common mistakes) will be emailed the following day.
