I have observed that many students simply don't know what they are doing when solving quadratic inequality.

They think that solving quadratic inequality is similar to solving linear inequality!

This is the biggest mistake!

Solving quadratic inequality is a fundamental skill.

Watch the video, learn the 4 steps and apply them on solving any quadratic inequality to see results!

I am bringing forward my plan to return to teaching after 3 years of break.

This Friday, I'll conducting a 2 hours revision class on O Level Additional Maths.

It is an online live! lesson for Sec 4 O Level and IP. I also welcome Sec 3 to join us. As this is a revision class, the teaching pace will be faster.

Due to limited seats, priority will be given to the Sec 4 O Level and IP students.

In this 2 hours lesson, you will learn

• How to score in Binomial question simply by using the given formula in the formula sheet! No memorising at all!
• 5 main types of questions and their respective strategies to reduce careless mistakes and get you the correct answers fast.
• The very important topic linked to binomial expansion and the most common laws repeatedly use in almost every question.
• Bonus: How to answer a real life binomial expansion application question on basketball games by focusing on the details instead of being stunned like the rest of your classmates.

About Me

Many of you might know me as the 10 Year Series Book Author for O Level A & E-Maths who have transformed hundreds and hundreds of students to achieve at least 4 grades jump in their exams.

I had been taking the O Level E-Maths and A-Maths exams with my students as a private candidate year after year. This got Straits Times curious and I was interviewed in "Math tutor sits exams to understand students better".

If you are looking to complete your Binomial Expansion revision within these 2 hours for your upcoming prelims, end of year exams, click on the link below to register for the complimentary online lesson.

Date: 10 July 2020, Friday (Public Holiday)
Time: 10am – 12pm
Fees: $120 $0
For: 2020 Sec 3 & 4 O Level and IP

As this is a revision lesson, Sec 3 students who want to learn this topic in advance will expect a fast teaching pace.

Webcam must be switched on when lesson is in progress.
Materials will be emailed by Thursday.

It is something we have learnt since lower secondary.

In 2019, GCE O Level Additional Maths Paper 2 Q10 tested candidates on their basic understanding of roots.

11 marks! Wow!

If you have been simply surface learning, you won't get past part (i) of the question.

See the video to see how I approach this question: https://www.youtube.com/watch?v=CPtbpO4At9w

• Quadratic equations & Inequalities (include solving simultaneous equations, sum & product of roots)
• Indices & surds
• Polynomials & partial fractions (factor - remainder theorem, solving cubic equations)
• Binomial expansions
• Power, exponential, logarithmic & modulus functions
• Trigonometric functions, identities & equations
• Coordinate geometry in two dimensions (include circle, straight line graphs, parabolas graphs)
• Proofs in plane geometry (CLT)
• Differentiation & integration

This first one is on linear law.

Basic concepts that you must know are:

• Equation of a line
• Understanding of coordinate system

In this video, I share with you a strategy I teach my student to make linear law easier to understand and reduce careless mistakes to a minimum. I called it "Capital Letter". I use capital letters to represent the complicated horizontal and vertical axes. Even my equation of line is in capital letters too.

Look at my video to understand my thinking process and apply it to yours when it's your turn to solve a linear law question.

This question is interesting as we do not have to draw the graph which is commonly asked in the past.

This question will cause your downfall if you are not absolutely clear on the concepts of linear law.
