So... about a month ago I got into my dream school with full funding. Great, right? This semester, meanwhile, I've been writing my undergraduate honors thesis, which I just submitted in final form to be defended, well before the final deadline.
I go to talk to thesis advisor yesterday, who informs me that they have not yet contacted the necessary outside evaluator. The advisor, who wrote a LoR for me, apologized saying that they had too much on their plate. Long story short, it seems that a committee may not be ready in time for my graduation.
I wrote about this project in the SoP to said dream school- and while in my discussions with faculty there it's not come up, of course I feel like I have to tell them if it will not be approved by graduation. It's possible that I could delay graduation and take on another semester to defend it, but this means a lot of extra money that I don't really have.
Is it a big deal? Should I write to them? Should I just not mention it? Should I ask my advisor to write the Department (but this feels childish)? Should I write them myself (but I don't want to embarrass my advisor)? It's not just a matter of them possibly rescinding admission- is this possible? - but also of course I want to start off on the right foot at dream school.
