Waitlist decision letter on May 4th

Hello guys, I am on the waitlist of CMU. On May 3rd I received the email of writing a 500 words essay, and I did write and submit it in time. On May 4th I received the decision letter saying that “We are unable to remove your name from the waiting list and therefore cannot offer you a place in this program. However, openings may become available during the summer”.

How many of you received this letter? What does it mean by “unable to remove”? Besides being offered admission, is there a kind of removal indicating you are totally declined by CMU? And is there really a chance that a spot becomes free in the summer?

a bunch of people got this letter, most (But not all) departments apparently had spots. unable to remove means you aren’t admitted and still on the waitlist. everyone who remains on the waitlist got the option to stay on the waitlist throughout the summer. you don’t know for sure a spot won’t open up during the summer, but i would say the chances are slim to none.
