I was surfing the web when I found this site who pays you for doing homework for students and vice-versa.
#Process:
1.go to the site called 'student of fortune' or click here : Homework Help, Online Tutoring in Math, Science, Physics, Chemistry from StudentofFortune.com - StudentOfFortune.com

2.find questions (home-works) left by students.
3.choose question which you can answer perfectly and submit.
4.It's a great way of earning if you are good with homeworks as some of them pays as much as $100.
