New update: After I didn't hear back from the Animation department after the College reopened after Easter break, I emailed Admissions querying the status of my application, and got no response. Despite being 99.9% sure that I had been rejected from the programme, especially after seeing the recent posts on this thread saying that some Animation applicants did receive offers on 12 April, I emailed the Animation administrator again yesterday, saying I need to make some major life decisions, and have had to put my plans on hold until I find out whether I have a place at the RCA or not. This morning she emailed me back apologizing that I had not received a response yet, and said that she would have the Registry office contact me ASAP. She also mentioned that there have been several power outages that have affected work across the campus. Many hours later (10pm in London - they must be working overtime), I got an email from the Registry office saying they sincerely apologize for the delay and..... I GOT IN!!!! They wrote that the delay was due to the fact that the new Narrative Pathway is not yet validated, but it will be in a few weeks time. I'm not sure if that, or the power outages really have anything to do with me having to wait 2 weeks for a response, but I'm just so glad the waiting game is over. It was excruciating.
They emailed a PDF of the official offer letter, and all the forms I have to fill out, and said they put the original physical copy in the mail today. Now to figure out all the details of moving to London!
