The authentication process may take up to 2 business days. You will receive a response with your discount code at the email address you provided. You will need that discount code before you can register for the course at the discounted rate.
Discounts cannot be combined. However, if you would like to use the SMC³ member discount for SMC³ courses and the Veteran or Student discount for general courses (if you are eligible), you can but you must apply for 2 separate authentication codes.
