I don't know if it's worth it.
Mostly because if you call, I don't think you'd speak to someone on adcom or even someone who would pass the info along to adcom
Maybe they'll respond soon-ish?
I emailed one of the contacts at a school I'm interviewing at on the 23rd and their email automatically responded saying the office is on holiday until the 28th. So give it a bit of time?
I can second this. One of the professors I've spoken to that is on a number of biology program adcoms at an Ivy institution said basically the same thing.
So this is mostly to appease the people with interview offers; things should mostly be okay!
