The resources below will help you improve your mathematics to an "expected" level ready for the start of 3rd Form.
Firstly we have some basic skills work:
Pass Learning Lighthouse 2, 3 & 4 (some of you will have already done this, so move to 5 & 6)
Regularly score 28+ on the Numeracy Ninjas
Work through these short "5-a-day" sheets (dates are suggested, you can do them in any order you wish).
Great websites help for use with your CGP workbook. Look at the 2nd Form objectives for the year and choose your weaker areas to work on from the workbook. Use the websites (below) to help.
Try your luck on these old FOUNDATION IGCSE papers (don't worry you will be doing Higher in 2023).
