Resources and practice tests to develop your maths skills

Online maths resources

Practice and develop your skills

Learn about a topic and complete tasks to check your understanding. You can focus on specific topics that you're struggling with, or work through sections to improve your general skills.

Reference and deeper practice

These resources are more useful as reference materials or to study a topic in a lot of depth.


EquatIO is a piece of software that runs on your desktop or browser and allows you to read, write and listen to mathematical material. It also has STEM and graphing tools.

Diagnostic tests

Use these short diagnostic tests to check your understanding or as a refresher on key maths skills required for the Maths modules in Economics and PPE courses.

If you get less than 60% in the tests, consider booking a maths appointment for advice and resources in order to supplement your skills.
