I have a weird memory. When I was in school, a teacher could be giving a lecture and if I found it boring (which I usually did), my mind would wander and I'd day dream and think about other stuff. Needless to say, I wasn't focussed on anything so when it came to answer questions or take tests, I'd be SOL because I wouldn't remember anything the teacher said. Once I got a laptop, if I was bored, I'd surf the web, play games like chess or majong, etc. I wasn't really paying attention to the teacher, but my mind was focussed on something. What I found out was that while doing this, the teacher could stop and ask a question and I would be able to repeat him almost verbatim. I did better on tests because I'd read a test question and associate what it was referring to, to what I was playing or reading about at that time and I'd recall (again, nearly verbatim) what the teacher was saying about it.
