Memorise quotes, often that's always a good way to prepare for the pre-examination period, on top of that, it'd be best to really understand the logocentric concepts of the topic that you're studying, often you need time to do this, so do it a few weeks before an exam perhaps? i always find discussions with peers to be most enlightening, because going by the saying "two heads are better than one" ultimately you might gather good ideas, that can related to your topic.
Often I also find myself writing practice essays, as many teachers say that is indeed a very good way to prepare for an exam, as you generally get that idea of what you're doing right and what you're doing wrong, basically if you spam the teacher with practice essays, it's highly likely you'll realise the main ideas you need to establish, and find what the markers are looking for, it's a good idea to give the "same" practice essay to other teachers in your school, as this ultimately provides a varied response.
Personally I like to ask my teachers to give me a mark for the practice essay, just cos, I can then set up a future goal, but that's entirely up to you.
You may then ask, Sir Eduard_Khil you genius, not everyone has that much time to write practice essays frequently especially when other assessments and exams are close by, well. As aforementioned by that panda looking fellow above, when I found myself lacking time, I would find an essay question and just write a thesis, which incorporated all my key themes and concepts I wanted to discuss, I found this method to be of great value, as it saved time as well as solved the everlasting conundrum of teachers saying "You haven't answered the question" this ultimately allowed me to identify key parts of the question, what the question wanted, and then answer it within one paragraph, as many people do say, the thesis is the backbone of your essay, which essentially is an argument. And what do you do in an argument? You make your introduction very powerful to prove that you are indeed right, and that noone should fuck with you.
Good day sir
EDIT: Do keep in mind this doesn't apply to unseen texts in paper 1, some parts can technically apply to creative writing, but I'll leave that to you, the esteemed intellectual being that you are to figure out how.
