I always make my own notes, even if that literally just means copying out of the textbook word for word - for some reason I can learn my own writing much much faster than someone else's typed writing. Use coloured pens if you want to make things a little more interesting and prevent the process from becoming too tedious. I then literally just learn everything I need to by reading over each page until I know it and testing myself without looking at the page before moving onto the next. It's a long drawn out process but the only way i've ever revised and it works well for me.

I personally have never bothered with revision timetables because I literally never stick to them and some subjects need a lot more revision than others so spacing things out equally only proves to be ineffective for me in the long run, but I know loads of people who do do them so they're obviously useful for some people. I also never bother making posters or condensing notes down into tiny pieces of information but again, many do, so give that a go if you want.

Once you feel as though you know everything though it's so important that you look at past papers and mark schemes on the website of the exam board. I can learn my entire A Level Biology course off by heart inside out yet look and a past paper and not know how to answer anything. You need to learn how they like to word exams / what they're looking for / the answer to questions you don't know.

Overall though if literally nothing is going in and you can't learn anything one night, put away all the revision and give it a go the next day. I go through some evenings where absolutely no information goes into my head and the more I try to force it in, the more agitated I get, so I just rest for the night and try again the next day.
