Original post by ExamParanoia@meWell, I don't know what level of Chemistry you're at, but I'm revising for GCSE mocks currently, and, although you may be way above me and this doesn't help at all, I'll tell you what helps me.
1. Past Papers. I can't stress enough how much the exam boards just recycle old questions (well reword them, anyway). If you've done all the past papers you can find (and marked them yourself) you'll find that your exam technique has improved drastically, and you'll - hopefully - ace your exams as you'll know the types of questions they use, and how to answer them to gain the marks.
2. Flash Cards. These are easy to make (you can probably find them online or something, or even buy them), and useful just to look at when you're walking from place to place just to give your memory a little boost.
3. Writing stuff down continuously. I find that this works better with languages, but it works just fine for chemistry as well. So if you find one of those annoying equations you need to remember, just write it down as many times as you need for it to stick.
4. Mind Maps. I'm working my way towards plastering my rooms with mind maps (and post-it notes, but that's point number 5). Just read a passage from the internet, or a text book/revision guide and then see how much of it you can remember by having a brain splurge onto that lovely sheet of paper. Then I tend to stick them on my wall, so I can lie in bed and think, huh, ethanoic acid= vinegar (well something slightly more scientific, but at the moment that's all I can come up with).
5. As mentioned above, plastering your living space with post-it notes. That way, every time you wake up you see something Chemistry, every time you make yourself a cuppa you see something Chemistry, even putting them on the bathroom mirror so that when you come to brush your teeth you see something Chemistry, and it gets hammered into your head.
Those are my main 5. I do use other methods (I even wrote a revision song for history..), so don't feel obliged to use these. I hope you do well with your Chemistry!
