Has anyone received an email from UC Merced regarding the Count Me In Program?
yes I did
I received the email invite as well. I believe those invited are the top 9% (calculated by the UC system) of CA high school seniors who were not admitted to any of the UC campuses they applied to.
My son is on the waiting list for UCI and UCR. Based on this information, it doesn’t seem like a good sign that he may be offered a spot at either school. 
My son just got accepted to UC Merced for Fall 2021 through Count Me In Program. Still waiting to hear from the other UCs. (Irvine & Riverside…but we haven’t heard anything).
