You can ask the online tutors at Course Hero for help whenever you need it by using the tutor questions option. And you will get two free tutor questions after creating an account with Course Hero, valid for 30 days. You can also pay $3 for tutor questions. In addition, depending on the membership plan chosen, each Premier Membership comes with a specific amount of tutor questions. You cannot exchange new tutor questions for cash; they expire with the expiration or termination of any prior subscription.
