Hiya ! so at this stage, I would focus, especially on everything that you don’t know in each topic. I’d also recommend doing as many practice papers and questions as possible, and having a look at Mark schemes to see where you gone wrong. It is probably too late to start making revision materials, but I’d recommend places like Quizlet on YouTube to have a look at videos and a lot of the resources and Quizlet already premiered depending on topics so I would have a search and see if there’s any flashcards that might be helpful for the topics that you’re struggling with. There is still time to put the effort in and as long as you revise smartly and prioritise areas that you might struggle with a bit more and briefly recap areas that you find easier in order to maximise your marks then hopefully you will be okay I’m wishing you all the best
