My husband's college roomies used to take notes in class and then right when they got home, re-write the notes..one, this was to reinforce that which they just learned in class and two, by rewriting the notes, you get a better idea of what the teacher is putting emphasis on. Whereas, the book simply details facts but doesn't make a distinction as to what topics are more important over another.. maybe if she does this and that which she is already doing, she'll do better..
good luck to her!!
