I hardly ever go to lecture. If there aren't any quizzes or tests, and attendance isn't counted, then I don't see a point. I read the book and usually do fairly well on my tests. If a professor tests largely on what they lecture then I make sure to get lecture notes and their study guide. And yet everyone tries to make me feel guilty for not showing up to a lecture that I will probably just daydream through.
I have a photographic memory and good retention so I'm not too worried about how well I am learning the material but somehow I feel I should feel guilty. I'm paying for it, so it is my choice of whether or not I show up, and irking the professor aside, I can't see anything negative about my way of learning. But it still nags on me when I miss. Is skipping a lecture really that bad?
