University of California portfolio reviews?

Hello, I am a community college transfer and I applied to eight UCs(not Merced). Six as an art history major and two as a visual arts major. I would like to see examples of portfolios that have passed review at UC Berkeley and UC Santa Cruz, but for some reason, nobody really posts their stuff online. If you have passed, or know of people who have passed, please share! Thank you!

Also, if you know how difficult it is to get into the other UCs as an art history major, please share that too!
I have a 3.7 GPA right now and no extracurriculars, but legend has it that you don’t need those as a transfer student. Is this true?
