o yea, my first D was also in calculus but in college, i took ap calculus in high school and got an A. but when i went to college i got lazy, cuz i knew everything but then i didn't remember the beginning stuff of the course that leads u to the shortcuts with derivatives later on.
ROFL thats funny, unfortunately in the UK our parents have to go to the school to collect these things, also gives teachers the chance to moan about you to your parents :// i do remember getting a report in infant school and it was bad (behaviour), i put it down a gutter :(, cant remember if i got away with it, think i did.
grade 12 calc... failed with a 27%...mainly cuz i skipped half the tests and the entire last 3 months of the course....didnt feel too bad cuz it wasn't anyones fault but my own... a couple weeks after that one of my friends said i couldnt get a 90 if i tried in calc...so the very next year i passed with a 96...
Hmm.. well I'm still in the twelfth grade, unlike you oldies, so I haven't really gotten a chance to easily get a low grade yet. But I have gotten 50% on a Physics quiz this year already, which is nothing to be proud about. =\
