how to get a 9 in geography gcse?

hi i am so stuck how to get one. in my y10 mocks i got an 8, and in y11 mocks i got a 9 , but it was GENUINELY fluke. and bc i got a 9 i am not allowed to go to the intervention, but i am struggling so much with it i don't know how to learn the content.
i do edexcel b, and the questions are always weirded kind of strangely and i don't know what i need to know and what i don't, like idk the spec is kind of confusing.
i am so stuck on how to revise and feel confident. does anyone have any tips pls?? thanks
