Math Exams #1

Yesterday I got back the results of my first two exams.

Prob stat - 96%. I missed 2 points by changing the correct answer into a wrong one. I missed another 2 points from thinking that the words President, Vice President, and Treasurer denoted four rather than three titles. (Well, it's four words.) Duh.

Linear algebra - 98%. On the morning of the test, I practiced doing proofs (of which there were two, totalling 30 points, on the exam) by attempting to prove all the theorems we had covered thus far in the book. By comparison, the ones on the test were easy, though I did legitimately hand-wave one little thing that deserved a point reduction.

But - yesterday in class, we were looking at the theorem the prof calls The Theorem of a Million Parts (it's only 12, really) and proving various parts of it, and he offered a bonus of 2 points added to the test grade of anyone who could prove this one thing, which I did manage to do. So that brought me up to 100%.

During the proving of the Theorem of a Million Parts, he had written WTS on the board and someone asked him what it meant. "Oh, that is 'want to show' - actually, I had thought I would just start using only the first letter of each word from now on. That would be fun, WI? I mean, wouldn't it? No? Okay..."

I hope I get an A on my linear algebra test tomorrow too. I'm jealous of you for your professor!

Tam, good luck tomorrow. I try to remember the occasional classroom tidbits so you can at least have something of the vicarious experience of a fun professor.
