Received this letter on 5/10/19. Sounds like a No to me:(
I am writing with an update regarding the waitlist at Case Western Reserve University. While we would like to have more of a clear picture of how our incoming class is shaping up, and would then know whether we could admit additional students or whether we should close our waitlist, what we are seeing right now is that there is a fair amount of uncertainty. In most years the next couple weeks of May are when things start to solidify, and we’ll have a better sense of whether we can extend additional offers.
We have already released many students from our waitlist, but since you are a student we would like to be able to admit if we have room, we have not yet closed your file.
We will be back in touch with an update in late May, and we’ll contact you as soon as possible once we know whether we are able to admit additional students or if we need to release the rest of the waitlist.
Thank you for your continued interest in Case Western Reserve, and please be in touch with any questions you may have.
