I dont think so.
See the following
If you’ve received a waitlist decision, you can choose to join one of two Waiting Lists:
The Priority Waiting List is for you if Carnegie Mellon is still your first choice. To choose this list, please select "Priority Waiting List" on the Waiting List Reply Form(opens in new window) and submit the Update Form(opens in new window) any time between April 7 and May 1.
The Regular Waiting List is the better choice if you’re more interested in other colleges but still want us to consider you for admission. To choose this list, please select "Regular Waiting List" on the Reply Form.
All waitlisted students can choose between these two lists. We don’t have any additional requirements for the Priority Waiting List beyond the Update and Reply Forms.
