They can also track the progress of their application and receive notifications (only available for certain courses).

The app provides exclusive campaign information for members and important notifications via push notifications. Members can accumulate, use, and exchange points, and receive cashback (only for eligible users). The app also offers AI support for resolving issues, easy access to the member support page, and columns filled with tips and tricks to enhance their lives.
