It was pretty rare that I DIDN'T turn in my homework, actually. Even if I procrastinated until the last minute, about 95% of the time, I turned it in. There were a few times in high school, however, that I didn't turn something in and my grade just PLUMMETED. I never really got in trouble for it, though. =|
A bit. I really do not, not do my homework that often. I usually try to get it done but if it does not happen then it just does not happen. I usually don't freak out unless it is a huge grade or if I do not understand.
My teacher gives me a half the credit when I do not do my homework. So if my homework is out of 20 points and I do not bring it in the next day, my teacher brings it to a 10/20. Anyway, I never get in trouble when I do not do my homework, but it will cost me.
