Got into UCLA but rejected from UCR?!!

I’m just REALLY confused how I managed to get into a top UC school and rejected from a lower ranked one. I had a 4.1gpa 1290sat 8 AP 4 honors courses, some volunteer work, 2 sports, and link crew. Anybody else get this lucky?

Also I got waitlisted at UCSB and UCSD.

Each UC is independent and although the 14 areas of application review criteria are the same, how they weight this criteria is different for each UC. Also, the schools are looking for student “fit” and UCLA must believe you will be a good fit for their campus.

Congratulations and which majors did you apply to for UCLA and UCR?

For UCLA I selected Computer Science major and physics minor
For UCR I selected Software Engineering major and physical science minor
