A level English Language revision

I've always found A level English Language quite easy, but when it comes to the exams i struggle. The last mock i did i got a D, and while my teacher says I can improve a lot in the time 'till the exams I feel I have to revise much more to get my desired grades, but my question is how does everyone here best revise for AQA English Language? I've going over paper 1 stuff right now, but im struggling.
