Real-Time Help from Real Tutors

The eChat tool is an easy, fun way to connect with a tutor for math help. Just like in a video call, you can use text chat, audio, video, or screen share, plus you and your tutor can work together on a virtual whiteboard. To enter our online classroom, just click on the name of a tutor in your subject area. If you're the first student in the classroom, your tutor will say hi, and you can get started right away! If your tutor is already working with another student, just hang tight: grab a cup of coffee and check back every five minutes. A standard eChat session is about twenty minutes long, so the tutor should be with you soon. 

To get started, watch the video to the right, and then head to our Log In page to sign up! 


Due to budgetary restrictions, the eChat tool will not be available in Winter or Spring 2017. We sincerely apologize for any inconvenience.
