Is there an admitted student day or anything special for Regent's Scholars?

I did not see either being specifically done to better attract admitted students.
Is that the case, or am I bad at finding it?

Ok. Sorry, my bad. Just found it: https://www.ucdavis.edu/admissions/undergraduate/events/decision/freshman/

April 6th.

Still, do they do anything special for Regents?

UCD has Decision Day April 6th. https://www.ucdavis.edu/admissions/undergraduate/events/decision/freshman

Another option is Picnic Day which is long standing tradition and much more fun than Decision Day.
Picnic Day is April 13th and if you plan to go, make any hotel reservations now if needed.

There is also Admitted Student tours throughout April.

@Gumbymom Thank you. Your patience and dedication to all the UC forums amazes me.

I am not sure if there is anything specific for Regent scholars, but if there is a special event scheduled, I am sure it is by invitation only so I would check the email and/or portal to confirm.

In 2017 there was a luncheon for Regents Scholars the Friday before Decision Day. The same afternoon there was a program for UHP arranged by the university, followed by an overnight arranged by the students in UHP.
