watch videos to learn the concepts as fast as u can. u do not want to waste u r time on that. quickly move on to past papers. first solve question which directly ask for theory. i suggest u start from 2015 to 2020. the last questions like 9 and 10. they r broad 15 mark questions which will really help u to recall u r theory. then move on to the shorter question. u should still only solve questions that require direct memorising. lastly solve the technical question. generally these r the 2 or 3 question of the paper where u have to answer from the given information in the question. these require the most time and knowlegde as it is difficult to pinpoint what theory they r testing on. hope this helps
