i hear you, but clever deal anyways. my laziness in high school definitely didn't prepare me for college. my high school geometry teacher started grading our homework after she found out i wasn't doing it, even though i was acing the tests. i still didn't do the homework, banking on the idea i'd get an A anyway. she changed the grading to make homework worth just enough to give me an A-. =\ short term thinking...
I owe my career to not doing math homeworks. School math wasn't something I cared about, but I wanted to make games so I learned programming instead of doing math problems. Ended up catching up with the math through gamedev anyway - it was very easy to learn once I cared about it.
In the end I had mediocre math grades throughout school, but learned a ton of skills I now use to create stuff.
