If you purchased the incorrect Access Code, you can still use it. Access cards function like gift cards. Depending on the amount on the card, there may still be either credit remaining or a balance owed.
When a student enters an access code to pay for course enrollment, the system displays the code's value and the program and provider level it was originally intended for.
If the code is of a lesser value than the enrollment fee, students can still use the code to put the contained amount towards the total and then pay the difference with their credit card.
If the code is worth more than the fee, students can still use the contained amount to pay the total, but they will have a non-refundable balance left on their access code.
