Some people just learn better from hearing, so the lectures are better for them, even if they seem redundant. But reading the book aloud isn't enough. Effective lectures sound different from books: shorter, simpler, more repetitive. Really, the right thing for a student to do is to read the relevant material before the lecture, then listen for nuances and ask questions in class. Of course, I only occasionally attained this ideal when I was in college.
