I really can't concentrate when I have to open a book. The moment I see a book open, my brain shuts. And I thought sometimes it's very difficult to articulate or express myself on paper, because I may be good at expressing myself verbally, but on paper it's another story. And I always felt that if I had the opportunity, for instance, to do my exams verbally, my marks would be much better, as compared to having to write them.
