Do what I do. Procrastinate, push things off till last minute, and then do a halfassed job at the end. 8D They wont know till they get your report card!
No but in all seriousness, using homeroom for homework and catching up helps, even though that kinda makes you antisocial for a bit. Id say use your spare... but... we dont have that yet, which kinda sucks. If you still have too much... why not just drop something if it's voluntary? Not the entire class, of course xD put your foot down and say "no" if there's too much being pushed on you, I did that in drama class when I kept on having to write the scripts for every. damn. character. 8I
Hope this helps, Nabs. D:
