In order to meet with any tutor listed on Wyzant, you must first add billing information to your account. This information must also be added in order to continue messaging any tutor to whom you've already sent a message. No charges will occur until after a lesson takes place.
Tutors decide if they are willing to conduct an in-person interview free of charge. Some tutors include this information on their profile, so be sure to check! If you're still not sure, you can use Wyzant Messages to reach out to tutors that might be a great fit for you and ask about a free first meeting.
