Concerning studying techniques I suggest starting Habits, rituals, you know. It always helped me a lot to have a certain beginning and a certain end of studying. It is important that you establish a border between work and your leisure time. For example take a shower before studying and work out or play computer games after studying, so that's what I did back then. On the one hand a goal in terms of a certain time, on the other hand in terms of a certain reward.
