What efficient ways of learning are there?

I used to be a uni student,,but I graduated just as average.

I was wondering what could make you a swift learner?

Nowadays, I am a hacker. So I learn constantly. What I do, is I absorb as much information in the shortest amount of time by watching/reading hacking tutorials through a superficial knowledge. -everything is kept at an introductory level.

That gives me a breadth of knowledge, and when I come to a task I try to complete it with as deep research as I can and with as much practice that I can..

In my opinion all that learning at uni, concentrates on 2 skills, being able to tolerate someone boring speaking for 45 mins and memorizing data.. - for me those two skills arent needed and they can maintain in the academic realm..

What do you think?
