Completing the square of a quadratic equation is a very useful technique that is used for solving quadratic equations(E-Math), finding the turning point of a quadratic graph (E-Math) and finding the center of a circles equation (A-Math). However, stu...

You might be studying for math or sciences, you might be preparing for O-levels or N-Levels. It is important to study hard and effectively if you want to do well. The following are some important strategies that we have compiled from some of the top...

Every year, there will be Sec 4 students (or their parents) who approach me one month before O-levels to help them with A-Math. Sometimes, their A-math knowledge is almost non-existent. Given the limited amount of time left and the vast extent of wor...

The fact that you are reading this article means that you are taking this issue seriously. Please do not ever sweep it away as “just another silly mistake”....

Are you having difficulty with remembering graph shapes of different functions? Graphs of power functions is a chapter in the O-levels mathematics syllabus and students need to know how to sketch all the core functions.

Under the O-level additional math syllabus, students are expected to know the values of several trigonometry special angles (Such as Sin30, Cos 45 and Tan 60 etc).

The standard chart given in all textbooks and notes will be as follows:
