How to use the site
Choose a module from the navigation. Then select a topic and sub-topic. Most of the questions are randomised, so you will never get the same one twice. When you are finished, click 'Start' to see the solution, one step at a time. You will need to log in if you want to see solutions and the marks awarded. It's free to register.
Teachers use these resources as extra material for lessons and examinations
Pupils use the site to get extra revision practice. Try to choose topics you know you are weaker in. On question pages you'll see the Timer button in the top right-hand corner - click it to test yourself against the clock. You will need to log in to use the timer.
