Demo or trial is given to everyone, even before buying a new product. Customers go for free demo because they don’t want to get cheated. Similarly, online teaching also provides a free demo class. After registration on the site select four suitable time slots within a week for the free demo. One of these time slots will be selected by the tutor when the student can have a demo session. A prior confirmation e-mail will be sent before the demo session. The demo class will be absolutely free and student can give review after the class if they are satisfied with the tutor and would like to continue with her.
