I study by writing a summary of the material that I'm studying. If the material is very comprehensive I do a summary of the summary. The shortest summary is the only material that I review before the exam. For example, if I had to study a whole book, I would write a long summary first, and then a second, shorter one. This technique works because first you have to go through all the material and understand it, and second everything you write down tends to be remembered much better than if you just read it.
