World history ugh...
Most Helpful Guy
Well, I study history at Uni, so I love the subject :-). The way I used to study for history tests in high school was to tell myself everything I've studied. In other subjects such as math, this doesn't really work but the cool thing about history (at least on a high school level) is that this method works really great. Just walk around in your room (walking increases blood circulation and blood circulation helps memorizing and understanding things! That's why the ancient Greek philosopher Aristotle always used to go for walks with his students in the vineyards instead of just sitting in a classroom). And while walking around your bedroom, talk to yourself about the things you need to know for the test. This can either be in a story-like way or it can be in a teacher-like way, where you're imagining yourself as a teacher, standing in front of the class and telling it to a bunch of students.
Apart from the walking around part, there are two really great and helpful things about this method. Firstly, saying things out loud makes it much easier for your brain to remember them. If you just read things, your brain can't process them so well. If you yourself are saying them out loud, your brain is paying more attention to these things and thus it can learn them much better. Secondly, by having to tell or "teach" these things to yourself, you easily notice gaps in your knowledge. Maybe you don't remember a particular date you need to know or perhaps you can't explain to yourself why something happened. When this happens, you can just go back to the book and look it up. I usually used to study 2-3 times before every test with this method. The goal is that you can just talk to yourself for half an hour or so and you don't have to look anything up anymore. If that is possible, chances are pretty high you will write a good mark in your test :-).1
