I have also applied for Nottingham and Bristol Gateway courses, applied for RVC but they didn't consider me eligible so wasn't accepted (even though I'm 99% sure I was, but let's not get into it haha) I had Nottingham interview on 16th November and have Bristol on 1st March.
My friend also applied for Bristol Gateway but hasn't heard anything back yet, so we can only assume that they've split it into definite interviews and maybe people on a waiting list? I'm sure people who are definitely a no would've received some kind of rejection by now, I can only think they are waiting for either confirmation that they have filled all their places or waiting for people to decline their offers, then they may offer others interviews for the course? The last interview date is the 15th March I believe so I can't imagine they wouldn't let you know by at least a week in advance so you had some time to prepare at least. I think its pretty unfair of them to leave people for this long if they're not giving them an interview, and don't see why they would?
As for Nottingham I read there's only 5 places on the Gateway course (not terrifying at all lol) but I haven't heard of anyone whose gotten a place yet who applied solely to Gateway so I believe that they are still making decisions and lots of people are still waiting for news. The only people who I've seen receive offers are people who applied for the 5 year course, and someone in another thread said there is going to be more sent out at the end of Feb so fingers crossed we will hear back by then!
