I've always been a very focused student. Lecturers usually provide good value to their students, but in three courses during my undergrad I went to two lectures before determining that my time would be better spent reading up on the material on my own. The lecturers were just very bad and obviously made an inferior job than the textbook. This is what is so good about being a student: You are for the first time allowed to take responsibility for your own results. Unfortunately you have to be lucky or extraordinarily talented to get similar conditions when you get out in the real world.
