One more proof that I can’t work with numbers. Got 147 / 200 on a math midterm.

Problem 1: The fact that I came up with a perfectly logical solution doesn’t give me full score. Why do I need to explain how I got ? That does not matter at all. Maybe I took a nap during the exam, and had a sudden vision of this matrix, which turns out help me to solve the equation. That totally doesn’t undermine the logic flow of the whole solution! 20 points out of 50 points for an unnecessary explanation.

Problem 3: So I am supposed to say that the associated system of the original equations is homogeneous. Seems like proving a definition can take up to 25 points out of a 50 points question.

Problem 4: I did explain both cases. The fact that the TAs deliberately / accidentally omit my second case, and write “What if ?” is just perfect and couldn’t be better.

Good game, TA’s. I’m all eyes.
