I did mocks in October and got a low 7 without any revision. I passed my 11+ so should have some sort of natural ability.
I have to make applications soon.
Obviously further maths is more difficult but more valuable, especially for universities.
What are your experiences?
Also, I am in the higher band of a public school out of choice, so am not in a grammar. I could go to a grammar school's sixth form if I get an 8 (I am eligible in all my other subjects currently)
