Can you tell your parents your dilemma? That you have a lot of summer homework that must be completed and you need more time away from home responsibilities so you can do this? Maybe you can set aside a couple of hours a day for homework by going to your library so you aren't distracted by home responsibilities or even stuff like TV or whatever your favorite distractor is. I tried that a couple of days ago and got a lot done. I went to the library, reserved one of the little study rooms they have, and went in there all by myself with just my books and notebooks for 5 hours and got a ton done. Going to try that again this weekend. Good luck. I hope your parents can help with the problem.
