First, please note that coupon codes issued directly by MIT xPRO staff and support cannot be used to purchase MIT xPRO courses offered in collaboration with Emeritus, Global Alumni, Simplilearn, or any other partner.
Please see the FAQ article I have a discount code, which courses can I use it for? for a detailed list of which courses and programs accept MIT xPRO coupon codes and which do not.
Once you have confirmed that you can use your discount/coupon code with the course or program of your choice, find your course or program in the MIT xPRO Catalog, click the title, and navigate to the checkout page by clicking the "Enroll Now" button. If you are not already logged in to your MIT xPRO account, you will need to do so, and if you have not yet created an account, you must create an account before you can purchase a course or program.
On the checkout page, first ensure that your preferred dates are selected in the dropdown menu next to each course included in your purchase, then enter the coupon in the field marked "Enrollment/Promotional Code", and click the blue "Apply" button. Please Note: Coupon codes are case-sensitive (they must be entered actually as they were communicated to you, with all the same characters, including capital letters) and you must avoid entering any spaces either before or after the code.
You should see the discount be applied to the cost of your purchase, reflected in the "Order Summary" box on the right side of the window.
Finally, click the "Place Your Order" button to complete your purchase and enroll in your course(s) or program.
