Course Hero It's a a Hoax, a Ripoff None Listed Internet
They claim to have over 300 tutors 24/7 to assist you with College Courses, but when you ask for help they divert you to another so called "expert" that will charge you an additional amount to work with you. The initial cost is around $60. for the first 90 days, and it automatically renews.
They offer no/$0 refund if you only use it for one day. You will clearly see the first time you use them that they are a fraud.
