Any way I can do my homework faster?

I go to school, and my teachers drop the homework bomb on me every day. I have a project to finish in 1st block, some workbook pages to do in 2nd, tons of math in 3rd, and God knows what my teacher will do to us in last. As soon as I walk in the door (4:45, on a good day), I get crackin’, but I always stop at 8:30! I only take one break to eat, and I do not distract myself. Any advice on how I can do it faster and finish earlier?
