UCI Regents and CHP vs UCLA

Hi,

How important or beneficial are the priority enrollment and CHP program? I took a gap year and got admitted to UCLA and UCSD as well but without Regents. With 8 APs with lowest scores of 4, I would love to be able to graduate early if priority enrollment is actually what I think it is.

My end goal is graduate school.

Thank you all in advance

What major?
And what qualities do you prefer in a school?

Material science engineering. I prefer close-knit, more faculty/student interaction type of environment. My goal is to finish bachelor’s as soon as possible and move on to graduate school. Easier As and more relaxed pace is preferable.
