Multiple AWS accounts and AWS Cloud Institute

Hello, I have multiple AWS accounts one of which was accepted into the AWS Cloud Institute program and I need to combine my accounts, I understand that its an issue but I haven't registered for any courses yet and completed the registration process is there anyway for me to merge my accounts and be able to finish the registration process? I also tried to apply using my Amazon employee credentials but when I try to go to the link to complete the intro course as part of the application process I receive a permissions block for the page.
