You have done well in your mocks! well done!
I think your very ambitious with your hopes for your GCSE grades.
For your science subjects I think your on track, I remember getting grade 5's and 6's during year 10 biology however at the end I achieved a 9, so I think the science subjects are easier to improve in.
The english and humanities subjects are quite difficult to improve in (from personal experience) just because it's not really one of those subjects where revising can improve your grade. However, practice makes perfect, so keep on writing essays and doing mock papers whenever you can!
Also, bear in mind a grade 9 is very difficult to achieve and is only for the top 1% of the country (or something like )that so don't be discouraged by 7's or 8's, they're still good!
You have a whole year to improve so don't worry too much!
Best of luck with your GCSE's!
