I have gotten the following: 987A*A*A*A*A*A*AB in my recent mocks, and I am sure with hard work and more revision I can reproduce and improve these grades for the summer. I got the grade 9 in maths, and 8 in english lang and 7 in english lit. So overall 8A* (equivilant) grades, 2As and a B). Is this good enough, roughly, for oxbirdge entry 2018?
