It did not seem personalized. They don't seem to be sending them out all at once though! A friend of mine received an acceptance yesterday in the evening and I received mine this morning. Ah good luck!!!
UC Berkeley WHNI acceptances started! I received an email earlier today about acceptance and it stated that more information about admission will come later.
On Feb. 19th I received an email stating that the "status of your application for the Fall 2021 Doctoral Degree Interdepartmental Neuroscience Gateway Program program at the University of California, Irvine has been updated," but that is the only correspondence I have had since the phone call. Wishing you the best!
