DD is currently year 9 but I believe they are doing the GCSE curriculum already as the class is quite advanced she is studying level 8 material in Maths not sure for Science - definitely high level 7, she has asked for some revision materials specifically for Maths and Science - can anyone recommend anything as I don't want to waste money on worthless materials. I've also told DD to ask the teachers at school but thought I might find some advice on here as well.
