Secondly, know the conversions to commonly asked questions, such as knowing how to convert from km/h to m/s. Here’s a quick video to help you to understand how to convert from one unit to another. 

2 – Learn math tips and shortcuts 

One of the biggest parts of maths is the trigonometry identities and formulas we have to grasp. Hence learning mathematical tricks and shortcuts can help you save time in your exams. Not to mention that as you continue to practice, you will build strong muscle memory around the concepts making it easy for your brain to understand and solve the questions faster. 

Firstly, we have the trigonometry values trick with just our hands! 

Secondly, percentage shortcuts 

Percentage questions may come off intimidating for those who are not confident and comfortable with converting. Here is a mathematical percentage trick that helps you work out percentages as quickly as you would for basic multiplication. 

You can find more of these types of shortcuts on youtube and online. There are plenty of math tips and tricks that you have yet to discover and learn! 

Knowing shortcuts or some math tips will help you save time during your examination and focus the time on solving questions that require you to put your thinking caps on. 

These are the types of preparations you can do before your examinations. It is important that you do not lose marks due to conversions and calculations.

3 – Know mathematical terms, constants and notation by heart

Geometry is a huge topic in mathematics too, it covers angles, triangles and polygons. Therefore, you are required to know the names of the angles and triangles. 


These are the required concepts for Geometry in the Emath paper. 

  • right, acute, obtuse and reflex angles
  • vertically opposite angles on a straight line and angles at a point
  • angles formed by two parallel lines and a transversal: corresponding angles, alternate angles, interior angles
  • properties of triangles, special quadrilaterals and regular polygons (pentagon, hexagon, octagon and decagon), including symmetry properties
  • classifying special quadrilaterals on the basis of their properties
  • angle sum of interior and exterior angles of any convex polygon
  • properties of perpendicular bisectors of line segments and angle bisectors

4 – Utilise your calculator to the fullest 

It is important to know how to use your calculator, here is a list of the approved calculators for the GCE O Level. 

Your calculator not only helps with the simple calculations, but they also have functions that you need to know how to use in order to make your calculator worth it. 

One of the approved calculators is the Casio FX 82MS. Here’s a video on how you can use your calculator to find the mean, standard deviation and variance. 

You can easily search up your calculator model and check out if they have any useful tricks on the calculator to help you in your examinations. 

Emath and Amath formula sheet

Student’s math tips

As a university student, when I know there is a given formula sheet (where not all the formulas are given), I would write down all the formulas that are not given on the same sheet. 

You may wonder why do so when you cannot bring that in. 

It is important to realise that the only thing you are given outside of the examination is the formula sheet. 

This is one of the most neglected aspects of sitting for an examination. The formula sheet could be the key to revision. 

Here’s a quick view of how one of my examination formula sheets looks like. 

Doing this and constantly referring to it when I study or attempt exam papers helps you to build muscle memory around the formula. 

Additionally, you do not have to constantly flip your books when you cannot remember the formula.
