Pros
You get to earn money just for selling notes and study guides to classmates. I already take notes consistently, so it's a win-win! I don't know why anyone wouldn't want to become an EN! It really only takes a few hours of work over the whole semester, and the more time you put in, the more it pays off. As a Campus Mentor, I can say that I've had a great experience and learned a lot about working for a company that is done completely online. They excel at bringing a community feel to the company and stay on top of any questions or issues. Overall, I think StudySoup is providing a great service, they are a great company, and I look forward to helping them grow even more.
Cons
It's still a start-up so I've learned to be patient and understanding that there are glitches and issues to work out. However, the company has a huge drive to help with them and improve the way they do things. You are paid commission for note takers who sign up under you, but there is not other direct compensation for Campus Mentors. They do have raffles and competitions to earn extra money, though, which is a great addition.
