After the free trial, monthly fee payment is required to continue/schedule the next class. There is no refund for the monthly fee paid. The program is 3 months long, and it is highly recommended that you continue for 3 months to get the full benefit of project-based learning. The projects may be incomplete & lost if the students do not commit to a 3-month program. With that said, you have the ability not to renew your monthly subscription for the project course.
