Yes, you certainly would at mine which usually comes around 20-30th best nationally in the league tables. In fact, with those grades, you would be pretty much spot on average at my school if not even slightly above,as overall average was 6A*s, 3As and 1 B. To do the stats briefly, I got 9A*s 1A as did 21 others, and 17 got a clean sweep of A*s, so that's 39 with 9+ A*s in a year of 200ish. 10% of exams taken were B or lower and 60% were A*. Don't forget places like Oxbridge look at your performance comparatively with the rest of your year, so yours will look particularly favourable.
