Refund policy

All of our paid courses include preview lessons, which allow students to have a pretty good idea of what the material looks like and whether it meets their needs.

We are also very clear about the fact that we do not promise that you will pass the qualification tests by enrolling in our courses.

For these reasons, we are unable to offer refunds on any purchases and any improper refund claims will result in immediate unenroll from the course.
