Your end of year exam can be anything in maths that you have been taught up to this point (so Year 7 and below).
The scheme of work for Y7 is shown. Use the resources below for general revision.
Use Learning Lighthouses 2, 3, 4, 5,
There are also some old Foundation GCSE papers that will help you with exam practise.
Look back through your targets to improve on and find them on Maths Genie and Corbett Maths.
Finally visit Corbett's 5-a-day (use the Numeracy, Foundation and Foundation Plus questions).
