I know it may seem downright impossible, but try to stay off Chief Delphi for a while. I know I check it more than Facebook sometimes, and with a similar course load (though I'm a sophomore), I find I can get a lot more done if I stay away from Chief Delphi, or even just shove my laptop under my bed. Out of site, out of mind, my mom used to say, and it's true. If you can't see it, you are usually not thinking about it. Like the homework supposed to be done while you're on CD. So, I'd say eliminate distractions as a first. I also recommend some things said previously on the thread, about waiting until you are feeling tired, because then you are more motivated. BUT, I wouldn't recommend doing that all the time. Like said earlier, you should try to do as much work as possible during school, and lunch. I know how the battle between eating with friends and doing homework t lunch feels like, but you've got to prioritize. Would you rather have your social time at a 1/2 hour of lunch, or during the entire robotics meeting? Plus, There are a great number of resources available at school for you, so if you may need any, lunch is usually the perfect time to do it.

School>Robotics, but as I always say, School=Education, and Robotics=Education, so therefore school=robotics (That probably makes no sense.)

WHat I'm saying is it's important to do both. While school is a bit more important than robotics, the education and experience you get from a FIRST robotics team is more valuable than most of what you can learn in school (that is, until Amir Abo-Shaer changes it).

Just my $0.02, but I hope it helps.
