Um, try to actually visualise it. Like, just don't blandly read, actually close your eyes and picture it in your head. Oh btw, also talk to urself cos u remember way more if you hear yourself speak ( research). So like, yea.. so when you visualise it, it'll be more accessible in your head ( not just bland this and that ). Becos, i don't think it's possible to remember everything..u gotta try to understand it, like put it into your own words becos after all, if u know how to say it in your own words, it's much better than memorising detailed info...
