I have spent 5 hours yesterday just to realize that the way i studied was wrong. I spent a lot of time writing down what was written in the paper. I should change the way I read the paper. Ok, let's say that 5 hours was not wasted. That 5 hours was the hours to show me that I did the wrong way to study. Next, i will try to read something in my head. keep asking myself what am I reading? What do I want from this reading! That's it.
