Course Hero - www.coursehero.com

I would definitely say that Course Hero has been a study aid for me. I regularly use all products on the site: documents uploaded by students, course specific study guides, tutoring, etc. I asked my professor once what she thought of the site and she said as long as I'm not blindly copying answers, it's a study aid. I used to use the course specific study guides a lot while II was taking general classes. The great part about the guides is that things are broken down in an easy to understand manner with infographics, videos, and reading recommendations. Some subjects even have practice problems. I found this super helpful when preparing for exams and quizzes.
