I interviewed at UCSF on Dec 8th and was called by Jesus,...I mean, Dr. Alexander, yesterday.
The following is what I gathered over the months. It's not a fact so please don't bash me if I'm wrong but I'm fairly certain I'm close:
UCSF goes in discrete cycles. They have admitted people on Dec 8th and yesterday, Jan 27th. I am unaware of other acceptances on other dates. If you do the math you will see that it is just about 45 days between those dates. Since I believe Jan acceptance have only 30 days to respond, I would guess the next and most critical acceptance cycle would be at the end of Feb or even very early March. I would not expect to hear much until then since they do not over accept (counting on people not to attend).
If anyone has knowledge contrary to this, please comment.
