Speech went well. Expected time 05:40:00; actual time 05:38:-- Did actually credit the quote to Net147. Didn't notice too many weird looks from the class. Glad I added in the Good Morning bit. Got marks for that, I think, since as soon as I said it, Caron looked down and wrote something on her sheet of paper.

Spent some 20min on one maths question. To find volume of revolution formed by area between two curves, one must subtract the volume formed by area under the lower curve from the volume formed by area under the upper curve. That is,
Total V = π∫f(xupper)^2 dx - π∫f(xlower)^2dx
Damn calculus. -_-'

Got pizza. Got yelled at several times by stupid juniors who can't be bothered to read while I was getting pizza. Why do I bother? 'Selective school students' they call us.
