Seriously, coming from a first year college student who was a bit too lazy, DON'T DO IT.
Its not worth it. On the internet and in some sub culture in school that I've seen, a lot of people just love to to be lazy. Hell, NG has a slacker's club. Trust me when I say, it sucks in the end and its that kind of attitude that will screw you later on.
You do your work when you get, and you do more than the minimum. School isn't there so that you can slide by and talk to your friends. Whether you realize it or not, you are preparing yourself for a later life. Unless you enjoy pumping gas or flipping burgers, do your work. Getting that A will help you get into college and make life a lot easier at home.
If you can't do it on your own, ask for help.
If there is a video game out there, it can wait.
If there is a movie in theaters, it'll be out on vhs during the summer.
And if its newgrounds, WAKE UP!
