I found that most of the time I didn't use notes anyway, even if I attempted to take them. It depends on the teacher, though. Some teachers will start out by saying, "There are three aspects of _____" and then as they lecture, they talk about two different things, or four different things, but not three. Or they'll go off on a tangent, and you think that's Point 3, but actually it's not.
I did have one university history professor who told us on the first day of class that the the tests would be multiple choice, and would cover ONLY what he said in lecture, and NOTHING in the $60 book we were required to purchase. His lectures were very well organized, but he read them from notes, word for word. So, for that class, I wrote down every word he said, as fast as he said it, including his many editorial comments, like, "The Declaration of Independence is a page full of pathetic whining, and is an absolute piece of garbage." In those days I could write fast because I didn't use a computer. Using a computer has wrecked my hand, so I can't write for an hour at a time any more, but only for a few minutes.
I HATE that teachers make kids take notes in school. My AS 11 year old learns just fine by listening to the lecture and that kind of thing. Requiring him to take notes just messes him up. He's so busy stressing over that, that he doesn't learn. Of course, learning isn't the point. The point is being able to spew forth the correct answers on the annual state test so that the school will show improvement over the previous year, and thus receive more funding. Every Child Left Behind. That's how it is in the US, at least. And to see how much a kid can carry in a backpack before he suffers a permanent injury.
