It makes lectures a waste of time. Anything you get from lectures, you can read in a book. Why can't professors do difficult problems instead in lectures, to make lectures actually WORTH IT TO COME TO? Does this have to do with the typical college student being not motivated enough to read the textbook by himself? *sigh* Many students just go by with what the teacher says, and doesn't read the content of the textbook. Honestly, it's causing me to skip class.
