GCSE Maths Grade 9 students. Watch
I got a grade 9 in maths (but with Edexcel). The key thing is doing practice papers and questions. If you already know some of the spec, you should be able to learn the rest in one year. As long as you practice a lot you should be able to get 7 or above
Thanks for the advice, it seems like past papers are the best way to go, did you know the exam boards have put up student examplers for GCSE Maths? you can click foundation or higher and see all 3 real papers taken by students, it also shows the marks they achieved and students who got full, half or no marks.
