Aahhh

Why did I all of the sudden get a lot of projects? I have my research paper, which I didn't procrastinate too horribly on; I only have my works cited page left. So that's not too much of a big deal, I know I'll get it done and turn it in and not do too bad.
My issue is my other classes. In chemistry, evidently everything is due by Friday. So I have four assignments to do tomorrow. Plus, my math teacher today said that he wants to give us a quiz on Friday. Our class went "No not Friday! We have a research paper to do!" And I think he thought we were joking. But we were serious. I'm going to get such a bad grade on that quiz becasue I still don't understand the stuff and I don't have time to study it! And I also have a homework assignment to do in that class, and one assignment in that class equals at least 3 or 4 in another. If I somehow manange to study, thats another 2 assignments worth of time/
So I have like 1+4+3+2=10. 10 assignments to do tomorrow. It's too much!
Teachers must have some internal clock that tells them when to assign homework so it will combine the best with other classes huge homework loads to create the optimum stress level among the students. Why else would they do this and not listen when we say "Not Friday! I have other stuff due that day!" Every teacher says, "You should put my class first." but that doesn't work! I can't have all 6 of my classes first!
