Study your unique way
This probably isn't talked about much. Some just assume if you have to study, you write notes, highlight those notes, and stare at the page. Well I see this a lot around the place. Personally if I was to do this kind of study I'd be passed out in about 30 minutes.
Don't get me wrong, some may find this kind of study method works. But for others perhaps not. The important thing to know is WHAT WORKS for you personally. For example, would you be better at making a bunch of audio notes and listening to that like podcasts as you walk about your life. Or would you be better at placing flash cards around the floor and walking around them while talking out load and moving them around. Or what about making giant mind maps and recreating them until you know it. Or perhaps creating 'teacher type' questions, and trying to answer them by either writing a proper paragraph down on paper or typing up the answer. There are quite a lot more study methods when you really give it some thought.
But you need to know which one works, for you. Check it out, and perhaps you can search for some learning modality quizzes to see what kind of learner you are... visual, kinaesthetic or auditory.
Feel free to send me a note on that.. happy to chat. :)
