Hey, I'm not too sure tbh, but I was given a rejection on a Friday. Someone pointed out that it seemed like rejections were mostly given out on Fridays and offers on Mondays (I think it was?) But tbh I doubt there's a strict pattern to it.
Also, if your application status on portico says "application received" then they most likely haven't even viewed your application. On the Friday I got my rejection, I saw the status change to "currently being processed by admissions aaa" and then a few hours later, I got a decision on UCAS track.
Honestly, just forget about it, let it be. Fretting will make no difference! If it's meant to be, then you'll receive an offer no matter what 🤧 best of luck!
