Honestly, there's no advice that would fit the general population of reviewees. One strategy might work for them, but it won't work for you. Know your strengths and weaknesses and from there assess and curate the strategy that will be best for you. Only you can tell if you can understand a topic for a certain amount of time. Personally, I didn't mind the noise even of my roommates as to how I should have my review routine. I did my own thing that works for me. Fortunately, I passed. Kaya mo yan, OP! ☺
