You can renew your current subscription 27 days after you register. If you do not change your course type during this renewal process, you can register with a discount code if you want to subscribe through the current course type. However, if you want to change the course type, course duration and course day, unfortunately you cannot use a promotional code. You can renew your current subscription by logging into your account 3 days before the end of your 1-month subscription and entering the promotional code in the Payments section.
