I took my last GCE O-Level Elementary & Additional Maths Exams in 1997.
16 years later, I'm taking them again.
All the best and see you at O-Levels!
Your Child's O-Level June Maths Intensive Revision Workshops 2013
Parent: With so many providers in the market for O-Level Maths tuition, how do I know which one is the best for my child?
Me: It can be a headache if you don't know how to choose carefully. There are 3 main considerations:
- How is the Revision Workshops being carried out to help your child?
- Who is conducting the Revision Workshops?
- What is the proven track record?
We all agree that your child will have so many more options when he performs exceptionally in his O-Levels.He can choose to go any Junior Colleges or course in any Polytechnics easily, without having to appeal and be put through unnecessary waiting time.
Since O-Level result is so important, selecting a right revision programme for him is crucial too.
If your child is struggling to pass A-Maths or E-Maths, he has about 30 topics to master in 145 days.
To save his time, I have already based on my experience, selected challenging topics with significant weighting in O-Levels Maths. Focusing on this set of topics will help your child to build up strong understanding in the concepts, topics by topics.
- Functions & Graphs
- Vectors
- Logarithms, ln & Exponential
- Trigonometry
- Differentiation
- Integration

I look forward in making a difference in your child's learning experience for O-Level Maths.

A-Maths: Solve a Cubic Equation by Synthetic Division or Comparing Coefficients - video
Solving a cubic equation is similar in some aspects to solving a quadratic equation, factorisation is in action.
In the two videos, I show you the step by step approach I took to solve a cubic equation either by synthetic division or comparing coefficients.
This concept is usually covered in Secondary 3 Additional Maths syllabus under Factor and Remainder Theorem.
Step 1 (same for both methods) : Guess and Check the first factor (with the help of the calculator).
Step 2: Find the Quadratic Factor.
Leave a comment to share with me which method do you prefer or usually use? I look forward to your comment!

E-Maths: Introduction of Angle Properties of Circle (Basic) - Video
This topic, Angle Properties of Circle is usually introduced in Secondary 3 Elementary Maths syllabus in Singapore. It is a very visual topic in which some students might have challenges "seeing" and "identifying" them.
I would like to first introduce the 5 Angle Properties of Circle:
- Angles in the same segment (are equal)
- Angle at centre is twice angle at the circumference
- Right angle in semi-circle
- Angles in opposite segment (add up to 180 degrees)
- Radius is perpendicular to tangent
I have shared these 5 Angle Properties of Circle in the following video.

For those of you who have challenges with this topic, tell me what are the challenges you face in the comment section below.
A-Maths Differentiation: Finding Gradient of Curve
I'm very excited to be working on the revised copy for the GCE O-Level Additional & Elementary Mathematics Ten Years Series (2003-2012) by FBP Publisher.
The book should be available in all Popular bookstores (Singapore) in early April. There's something new on this book. To provide more value to students, this year we have included an additional book of drill questions.
I would like to share one of the questions from Differentiation: Tangent & Normal with all of you.
Skill required:
- Quotient rule
- Gradient of curve is dy/dx
Bonus: Strictly decreasing function means dy/dx < 0 for all values of x.

I would like to hear any comments from you. Did you do this question using another approach? Leave me a comment.
Pi.z.z.a Maths (cool stuff)
I came across this interesting image and would like to share with all of you.
This is to do with finding volume of a figure (example cylinder).
Volume of cylinder = PI * r^2 * h
r: radius, h: height
In general, to find the volume of a cylinder (or prism) = cross-sectional area * height.
