I received the Uni offer on Feb 8, and got an offer from Exeter (second choice) on March 17. Hope that helps you figure out a timeline. I think you all from the third gf should be hearing from colleges within the next week or so, but the website does say that final allocation can in some cases take considerably longer. I suppose towards the end of the spring, things have started to fill up. Hang in there, it should not be long now!
