Bored

I've been studying since 10 am. It's 6.38 pm now. I am bored. I am at lecture 20 of 29..so I have 9 to go. That's still a bit. Boo. The headache isn't helping. I actually have to try twice as hard to focus on learning the various types of pumps. Hmm. Come to think of it, I think I've forgotten half of them. Nuts. Let's see, dynamic centrifugals with axial flow and turbines....then we have reciprocating ones which are erm, piston, plunger and diaphragm and rotary ones which are gear, screw and erm, hmm, i want to say mono pumps. Yes, am fairly sure I am right. See how fun engineering is?
