This web site has been created as a companion to the booklet of questions that your school has given you to work on.
In the 'answers' tab you will find scanned copies of the questions with the answers.
Only look at the answers after you have had a go at the questions yourself. If you would like more detailed video tutorials of the solutions, click on the 'videos' tab.
If you would like the questions that the pupils are doing in the videos please request it through the 'Contact a tutor' web form.
