Hey people,
I saw this thread and thought I should probably reply.
I got natta from Imperial until an interview letter telling me to come to an interview in two weeks time (Mid-end October). Then I went to the interview and 2 weeks later I get this generic letter, auto-generated saying something about decisions in January, then 1 day later I get a conditional offer.
Studying, MSc Physics, 4 year course.
So yeah, don't be disheartened if you don't get anything from them for a while.
