Can confirm Chegg is a major buy for students. It has answers to almost every question for online quizzes, hw, etc. that students are required within their college courses. Just purchased a chegg and coursehero account after 4 years of school.

Okay so now I feel old but when I was in college, Chegg was just a textbook rental company. Like you mail in a hardcover book back at the end of the semester. 
  
 Is sounds like it's bacislly an online courseware system now?
