Yea troy, I usually only do what I can finish in Lab(we have block schedule, so we have 8 classes, 90 min each, 4 a day, and everyone's 6th block is Lab, where you can finish homework and go to other teachers and stuff). Or I'll just finish it in class if I can. I'll only take it home if it's something that can only be done at home(like typing something up or something). People say that grades show how smart you are...wrong! Grades(HW is a lot of your overall grade in a class) only show your effort, if you do no work you get a bad grade, that doesn't mean you're stupid, it actually means you're smart for not wasting your life doing work that just gets thrown away.
