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! :)

A-Maths: Quadratic Equation - Sum & Product of Roots [video]

Quadratic Equation is an important topic in O-Level Elementary & Additional Maths.

Different areas are covered for each Math. For example in Additional Maths, we learnt:

  • Discriminant
  • Sum & product of roots
  • Relationship between line and curve

I would like to share with you a question sent to me by a Secondary 3 student on sum & product of roots.

This topic is taught in the beginning for Secondary 3 Additional Maths.

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.

Other than feeling excited for our students' results, I would be eagerly awaiting my results as well since I took the O-Level Additional & Elementary Maths in 2013.  Read about my experience here.

I believe many students will be feeling nervous and excited at the same time. It's finally the time to see how much their hard work in the four years of secondary school education will pay off.

I would like to wish all my singaporeolevelmaths readers who are receiving their results on Monday all the best! May you have a memorable experience!

Regardless of the outcome, life moves on so make the best out of it!
