So, I wasn't late. I got there in time. And even then the lecturer didn't start the class until ten minutes overtime. He waffled for fifteen minutes on crap I already knew then spent half an hour talking about stuff I did need to know. Arsehole. I'm beginning to suspect the first half of this subject was all busy work. It's only now that we're getting into the theory we need. But the busywork crap will be on the exam, I bet. Fucker.
