i just rewite my notes and highlight keywords and then write them up again on here as revision notes/cards that way you are reading over them 3 times, i have been doing this for years and it works for me but it depends on really what is best for you
I just had an exam now and because my exams where like after each other i had to literaaly cram everything and i am so happy i did because i just did an exam and i feel that i got a high B or maybe an A. The paper was so nice still cannot believe it. The exam was AS info2. This is the second time i am retaking it. the first time i got a D by just revising a day before the exam but instead this time i literally crammed every single damn thing in the book. I believe that you should look for revision notes online that is what i used and after that test yourself by trying all the apst paper questions. FEEEEEEUUUU!!!!! tHREEE EXAMS DONE, TWO MORE TO GO.
