We worked on some past paper questions today and I would like you to try these at home if you were unable to make it to school.
The attached pdf file contains 2 past paper questions. The first question is Q24 from the 2008 paper, the second is Q25 from 2007. Please attempt both questions. If you get stuck, leave a comment on this post and I will get back to you. Next time you are in school I will hand out copies of the specimen solutions for you to check your progress.
