Math.
OMFG I was doing this math test. Fuck I feel like an idiot. It was Square roots and some prameter thingy. So when I started I looked at this number, I had to find the square root of 8456. So I look for that symbol on the calculatore, I couldn't find it. I was like "FUCK! This is gunna take years". So like 1 third through my test and 3 thirds through the test time. I saw the fucking square root button, fuck I was so pissed of at my-self. Anyways I aced the test =P.
