Just came back from that chemistry exam. I would've done a whole lot better had I known/remembered what a mole is and how to handle it. Hmm. I was able to do 2 of the calculations and I think they were right too. Unless I get minus points for not multiplying the results by 100 % before I gave the answers in percentages. We were taught to do it but I don't see the point. Like, "0.5 * 100 % = 50 %" etc. But I just do "0.5 = 50 %". Isn't multiplying by 100 % pretty much the same as multiplying by 1 (which is pretty much the same as not doing anything from my lazy point of view)?
And then I answered some other questions where I had to explain stuff. Let me tell you, explaining things can be pretty tricky if you don't even understand the stuff yourself. I don't really have any idea if I'll pass or not. And there's still that essay I need to write. Hrrr.
I missed a Swedish lesson this morning. Contrary to my habits, I didn't spend it dallying around online but doing my homework for the previous course. The assignment is a few days overdue, but I should be able to finish it today. :)

Here's a nice little math puzzle I just heard:
"A mother is 21 years older than her child. 6 years from now she'll be 5 times as old as the child. Where is the father?"
I'll reveal the answer later, since that seems to be the fashion. :P
