My guess (which is probably correct) is that they interviewed a whole bunch of high stat applicants in the end. So that come 4/30 if they see they have no As they can give them one knowing they will obviously matriculate. However, I do believe they aren’t just replacing everyone who withdraws with these people, to me it’s just a coincidence that the last two were from 4/16. I read somewhere a couple weeks back that UCRs waitlist while it is “unranked”, it is also secretly holistically ranked. Think about it UCR always wins an award annually for being “the most diverse”. It only makes sense that when one person from a specific demographic eg (gay, Latino, low ses) withdraws they do their best to replace them with someone on the wl with the same profile preferably with high stats lol. It’s all a numbers game to these schools so odds are if they see you haven’t PTE else where and you are a high stat applicant who checks the boxes they are looking to fill they’ll choose you. This is because they also want their yield to stay high (number of those who accept the offer they give them). Lets Just hope and pray, while still being happy for those we see come off the wl whether they came off on our date or a later one 😋
