Year 9 Revision - 9A1

Right then Maths Genius's - Here are some things to help your revision along some more.
From Tuesday's lesson here are the topics you will need to know for the test.

Here are the questions from the lesson so if you didn't finish you can work them out.

and here are some more test based questions with a Mark Scheme so you can see how you did.

REMEMBER - Don't keep revising what you are good at.  Remember which topics your weaknesses are in and revise those first!
