I really want to get a grade 9 in maths as its one of my favourite subjects and one that I want to study it at a level, but I seem to keep getting stuck with 7s and 8s. Unfortunately I haven't got my mock results back yet (and won't be until the end of the month) so I don't really know where I'm at now or what I need to work on. So, does anyone have any tips on how I could get closer to achieving a grade 9 and revision websites/videos that could help?
