Hey Hana,
Just wanted to let you know that you are not alone in this journey. I have been predicted all 9's and I feel confident that I can achieve the grades in these subjects:
English Literature, English Language, History, Geography, Computer Science, Biology, Chemistry, Physics
I did the Math and Arabic GCSEs two years ago and achieved an A* in both.
If you ever need any help with revision and studying for your upcoming mocks, don't hesitate to inform me and I will try to help as much as possible.
