No evidence, but “random“ makes no sense. Basing it on individualistic factors doesn’t necessarily add merit. There can be two people with equally impressive yet different experiences yet one may help balance the class out more than the other. Just my theory.
To me, that reaffirms what I said above: once the waitlist comes out, we will know for sure that the last cycle of offers - including the holistic round - is done. The only offers to follow will be from the waitlist.
Last year, the last round of offers (including holistic admits) went out on 4 Apr and the waitlist came out on 10 Apr. This year it appears that the last round of offers went out on 7 Apr. I expect people will be informed that they’re on the waitlist in the next few days.
