[AE] I completed my registration and it says that I have been added to the waiting list. What does this mean?

Once a program has met the enrollment capacity, participants who register up until the enrollment deadline will be automatically added to the program’s waiting list. Should additional spots become available within the program, participants will be promoted, in order of registration, from the waiting list to the main list. Once a participant is promoted, they will receive an email notifying them of this promotion as well payment details and will have 24 hours from the time of the promotion to submit their payment for the program. Should a participant fail to submit their payment within 24 hours, they may re-register and be added back to the waiting list.
