is it possible to score all 9s in gcse with these grades from mocks

biology-8
physics-8
chem-p1-7, paper2-9
maths 7,6,6
english lit- 9, 6
english lang- 9, 9
r.s- 9,7,6
goegraphy-9, 7
psychology-5,6

its possible but ur gonna need to work rly hard. English lit is a rly good improvement tho well done. Personally (bc I'm aiming for all 9s as well), my strategy for me is to focus on the subjects you seem to be bad at, like psychology, and absolutely hammer it (I got all 9s in my mocks by doing it this way), and make sure subjects like English lit that we get 9s in but we know are hard. You will be fine for bio and physics, and chemistry I doubt will be too difficult for you either.
Good luck!
