Summarise your notes
Learn your notes
Check the revision PowerPoint
Test your learning by attempting worksheets and past paper questions – you should spend the same amount
of time on questions as note making
The revision PowerPoints can be accessed on the school website. They contain summary notes, worked examples,
past paper questions and solutions. To open each PowerPoint, click the read only option.
In addition to the PowerPoints, you will also receive a folder of past papers. It is essential that you test your learning
by attempting these. The majority of papers included are from the previous specification, but most of the questions
still apply:
