Notes are supposed to be simple and easy to read, you right down what you need to remember and that's all. When your doing notes learn a part of the module, say Atomic Number, and then write it down as you think of it, don't try to do it word for word.
It's useless if you're going to make a copy of the text book on paper, if I did that I wouldn't be able to remember what I had wrote. Do definitions word for word at the end of your revision.
Notes are to help yourself not to memorize the book perfectly, at least that's how I learn.
Edit: I don't learn much in class when I copy from the board either, I have to go back over it and make my own notes.
