I am a C grade student, I'm close to a B according to my teacher, but I don't feel as if I am. I have tried so many times to revise for maths using online activities and revision books but I they don't help me at all. The best way of revising for me is someone there helping me through but my parents aren't good at maths and I can't afford a tutor. I am getting the maximum amount of help at school they can give me but I feel like its not enough.
Whats the best way of revising and learning maths outside of school? Please suggest any books or websites! Thank you in advance!
