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! :)

Differences between O-Level Additional Maths new and old syllabus

For Secondary 4 or 5 school candidates (in Singapore) taking the O-Level Additional Maths this year, many are likely to have registered for the new syllabus 4047. 

In this post, I would like to highlight the main differences between the new (4047) and old (4038) syllabus:

  • Matrices, Factor formula are excluded from the new syllabus
  • Intercept, Intersecting chord and Tangent-secant theorem are excluded from the new syllabus
  • Sum and differences of cubes in Polynomials are included in the new syllabus

Sum and Differences of Cubes New Syllabus for Additional Maths 4047

In conclusion, since there are more exclusions than inclusions. We should be expecting more application questions which can be linked to everyday life applications in the fields of Biology, Chemistry, Physics, Engineering etc.

The keys to achieve distinction in O-Level Additional Maths are still:

  1. a solid foundation in basic concepts,
  2. well-equipped with application strategies,
  3. wide exposure to carefully selected application questions,
  4. good management of time for doing and checking
  5. exam-smart strategies

A-Maths: Factor-Remainder Theorem Introduction Videos

For many Secondary 3 A-Maths students, this topic called Factor - Remainder theorem or Polynomials is usually introduced in the first 3 months of the year.

In this topic, they are introduced to the method to find the factors of a cubic equation so that it can be solved. They also learnt when and how to use Remainder theorem to find the remainder when a dividend is divided by a divisor.

They also know to rewrite an expression into function f(x).

In the following two videos, I use less than 6 minutes to bring across the concepts of Factor theorem and Remainder theorem.

I hope through these videos, you will have a better understanding of these two concepts.

Also, I have included a page which contains all the O-Level Maths videos I have produced since 2007.
