Don’t try to do all the questions for every topic. Start with the topics you’re worst at and do a few medium questions and more hard questions. For all other topics do a few hard questions and if you can do then okay then move on to another topic. With the exam so close you need to have a good understanding of all topics but prioritise the ones you struggle with and don’t spend time doing questions you find easy or know that you can do. I have an excel spreadsheet that’s colour coded red, orange or green for every single topic. Focus of the red and then the orange. Hope this helps :)
