Grade 9 in Computer Science: Is it Possible?!

Good afternoon, I hope results day has gone all right for you all! I have a question for the year 11s that achieved grade 9/8 in Computer Science (specifically OCR):
how did you do it?!?
I'm about to start Year 11, and a little worried about CS as it's my weakest subject.
For reference we did the 2023 Paper 1 as Y10 Mocks and GRADE 8 was the highest grade in our year. (it was one mark off 7..) Most didn't get above a 5, and I'm starting to think grade 9 is impossible. Paper 2 isn't bad so far, but that's because we haven't covered much of it yet )
I am aware of and do use resources such as CGP revision guides, Craig n Dave, Isaac CS, w3schools etc but its a bit too much lol.
If you've made summary/revision notes during GCSE, I'd really appreciate if you could PM me! Or advice on what revision resources actually work, and what doesn't. Or anything really ;(
Thank you!!

I got a 9 in cs and I use the syllabus to revise mostly as I found the subject very content heavy, like if you don't know the exact words or concept there is no way to gain marks. Closer to the exam I used the textbook to go over more difficult topics. Knowledge retrieval is rlly important using a whiteboard or blurting. Additionally going over past papers was so helpful like I did all of the past papers possible and went all of the mistakes; this includes any mocks where focusing on issues is crucial.

Thank you for the reply! I will definitely try blurting more, rather than rote memorisation lol. It's also true I have lost marks due to not using a super specific phrase ☹️ Thanks again for your support, and well done on your GCSEs!
