@kasdeya speaking as a college-level instructor (but really, this applies to school at all ages): please do follow this advice for schoolwork. Did you procrastinate on the assignment and now you have something that you know is bad, and you'd almost rather not turn it in? Did you oversleep for the test and now you're feeling like it's best not to show up at all? Please just make an attempt and submit something! If you do a really bad job, but still attempt most things, you can often get an F for that. That sounds bad, but a typical F is anywhere from 30-50% credit. Meanwhile, if you don't turn in anything, you're getting a 0. And there's a world of difference between a 0 and a 40, especially in terms of you're final grade (using typical "add-em-up" logic, which is actually pretty poor incentive design, but that's another post).
