I always dreaded homework back in high school, but who didn't? I got into a routine, which made it manageable, but I always made sure I got it done as it was graded and also helped me a bit towards my tests, and also reduced the time for me to study. I didn't realize how important it would be in college. Most of the classes I am taking now depend on the homework for the tests. The professor might take questions directly off the homework or come up with similar test questions, worded slightly differently. Knowing this, I just do the homework ahead of time and use that to study.
If the homework counts towards your overall grade, just do it. Manage your time out and take on certain number of questions each hour. Use the remaining time to study for your finals. My friend actually had 11 pages of online Calc 2 homework and left it off for three days before the deadline. He failed to study for his exam and could barely get through everything, which counted towards his final grade.
So just manage your time and get through as much as you can. Don't wait to do it until the last few days, because you never know how beneficial it might be towards helping you in your finals.
