I was curious if anyone has been accepted to any UCs yet?
no
They don’t give out acceptances until Marchish.
The earliest you will hear from a UC is End of January/Beginning of February which is UCR. UCM will sometimes post acceptances starting February and UCI starts posting rolling acceptances end of February (this from past experience). The majority of UC’s will post acceptances in March.
Yup! UCR accepted me in mid January last year.
