Bull-fucking shit. The closer you get to your thesis the less valuable classes become.
That's when you begin the one-on-one with your professor to find out what the hell she wants to see in your thesis in order to make hers look even smarter and more influential. That's why I spent more time than I wanted to studying Object-Orienting...
Except there's no test to take and your adviser doesn't get to do anything but review. You get to write a long paper, a bibliography and a billion footnotes for something that is going to sit on a shelf forever and never be read again after they say, "good enough".
