no linear algebra exam back

i kind of wish he wasn't absent tonight so i could get my exam back... i'm still confused about dual spaces ><

linear algebra exam

ok, so i spent thursday of last week up until right before the exam tonight (5:10pm) studying for it. towards the end of it, i was off the walls driving myself crazy. it didn't help that i drank a large cup of really really sweet hot chocolate, but it was worth it cuz this one only cost me $2 (the ones i usually got cost me $3). it was crazy cramming and we (me, rae, allan, and some times john) kept going over invertible matrices and the change of basis matrix.

guess what? none of that was on the exam. in fact, i don't even know what the exam really tried to cover because there were questions on there that i could not figure out how to apply what i learned because i've just been going over change of bases so much. one thing tho that everyone (ok, me, john, and allan) agreed on was that question 6 was ridiculous. we couldn't figure out what we even had to really prove!

yea, this exam makes me feel like i know nothing. absolutely nothing.

First Linear Algebra Class

was actually quite enjoyable. the prof went really quickly through the review of jargon. he seemed quite receptive to questions - started class late and ended it early because he wanted to watch the US Open. hahaha... i feel more at ease with linear algebra than analysis even tho i the last time i had taken linear algebra was the spring semester of my first year of college and analysis was fall semester of my senior year. proofs just aren't my thing!! i'd rather be computing and calculating than thinking about how to prove things.

i'm going to bang my head against my desk for a while now...
