BOB?

i saw ahn's post and assumed that we just write something up. so the test is tomorrow, i think, even though bob is not up....or is it?! well yes, i'm still unsure about some things but i think i can manage. i just have to review and study more. everything we learned so far is review from last year but for some reason, it's just not sticking. -_-;; i never learned the unit circle but since everything is about patterns, it shouldn't be too hard right? WELL WE HAVE THE TEST TOMORROW. I HOPE EVERYONE STUDIED!
