I have an in-person, timed, closed-book exam where I have to answer an essay question. The topic can come from any material we’ve covered since the start of the year, so it’s quite unpredictable and stressful. Does anyone have advice on how to effectively prepare and revise for this kind of exam? we’re allowed to bring an A4 cheat sheet, but since the exam is essay-based and focuses more on theory/ discussion, I’m not sure how useful it will actually be for me.
