I compltely disagree with a lot of what is written ehre. But bear in mind, different revision techniques work for different people.
I'm a law student, and i'll tell you how i revise.
First off, it isn't fun, and you have to spend a lot of time on it if you tuly want to remember stuff.
I never use gimmicky cards and post-its and things, they just don't work for me. I never try to temember all the details of cases- this is USELESS. You DO NOT get marks in an exam for writing about the names of the people in the case, and giving a whole description of all of the intricacies of the caes. The examiner doesn't need you to relay everything- they have the cases themselves! With ases, read them well and write notes on them, and just remember the basics of what happened, and learn the ratio by heart. Obiter stuff can come in handy, but don't fucos too much on it. If i must be more specific, the ratio is the reasoning behind a judges decision- the legal reasoning. If you are talking about a case, simply mention it by name, give a brief description of what happened, then focus on the ratio. To remember cases, simply learn a line of each by heart, and once you've got that ine written down, everything will flow back to you.
Use the textbooks. Where else are yo going to get the information from? As long as the book is up-to-date, with new laws, amended legislation etc, everything in it tends to be okay. I don't rely on tutors and lecture notes- lectures are often boring, and a waste of time- it all depends on the lecturer, who will only ever outline things anyway. The textbooks go into much further detail
The first lot of your revision is the worst- write EVERYTHING down. Then next time, condense. Then condense again. Do this a few times, until you can fit notes onto two sides of A4 for each topic. Again, if you do this, when you remeber a few sentences from your notes, things click in your brain an it all flows naturally onto the oage.
Start a few weeks before. Work in the morning, and break, then do more in the afternoon. Don't revise at night- keep evenings free for fun with friends, and you won't feel bogged down. Its not good to start revising at night, when your head is filled with the day's events. Easily distracted, good TV, tiredness, all these affect your ability to work in the evening.
Don't read loaods the night before, because this will stick in your head the next day, and it will be harder to remember other things.
Quite simply, reading a lot, and writing a lot,and condensing the notes is the best way to revise in my opinion. I hate cards, post-its and diagrams. But thats the way my brain works!
Oh, and listen to classical music while you revise. Its soothing, and makes you feel intelligent, and if you feel clever, and have the optimisim, you don't feel as hopeless- its psychological. Plus having music in as you reise(with no lyrics to sing along to!) will stop you from focusing on dstracting noises, like the drips of taps, banging from your flatmates etc.
