Thanks for your reply's :) usualy I study the best at home or in my dorm room, but when I don't feel like learning I'm usually wasting time on my computer. Next time I'm going to go to the library :) I'll probably learn more in the library than in my dorm room, thanks for the tip :) I'm already using a study plan, but because I always over estimate myself it doens't work that good, now, when I plan to do something on 2 days, I just add 1 extra day because it's usually not finished in 2 days :p
