Wow, that's a good way to pass..
or you can study hard and work your ass off!
Haha, btw Another tip that my sister told me (She did it herself with friends):
In Math class, steal the Teacher's Answer booklet and you wont even work (unless you have a very smart teacher..).
Anyways, She stole the answer booklet and everyday for 2 weeks in math class, they just sat there and talked. Was "Free time". Haha!
