>If you don't do the reading and study the material you need to know before the class it's covered in, then of course you won't understand what the professor is on about and of course you'll fall behind. I don't think I've ever done this aside from explicitly assigned readings for something like an English class. I've always either found the explanations given in-lecture on a topic the first time to be fully sufficient, or had to fill in a few things by reading the book after class.
