# Maths revision: Guides that might help

## Nobody but the exam boards know what is on the exam papers before they are turned over on the big day. When it comes to a subject as broad as Maths, it can be tricky to know where to start your revision.

We chose a few topics we thought might be useful to get you started. We can't guarantee these topics will come up, of course, but they're a good place to start. Click on the images below for the relevant revision guides.

All our Maths guides are exam board specific so click here to find your GCSE exam board.

## Fractions

Fractions, decimals and percentages are an important part of the curriculum, especially when it comes to converting one to another.

This guide shows you how to do just that. It’s an important part of problem solving that could save you any stress in the exam hall if the subject is on the paper.

## Algebra

Algebra is a subject generations of students have been tested on. There’s a lot to remember when it comes to variables, equations, expression and identity.

This guide leads you through the elements step-by-step in case you’re still a little confused.

## Ratio

Ratio is an aspect of maths learning which is pretty good real-life learning at the same time.

If you’re ever baking a cake you need to understand the ratios between the different ingredients, or even if you’re sharing things out. This guide takes you through the fundamental elements.

## Vectors

If you can get your head around vectors then you have a useful tool for tackling geometrical problems.

It’s all about the movement from one point to another and vectors can be negative as well as positive. Our guide also shows you how to use scalars to multiply vectors.

## Probability

The certainty behind an event happening is what probability is all about. It can be shown as a fraction, decimal or percentage and helps us to determine whether something is certain to happen, likely to happen, or in some cases, an impossibility.

This guide will take you through it all step-by-step.
