Every year my D’s small private high school has students accepted to Ivys and Ivy-equivalents who didn’t get into UC Berkeley. UC Berkeley cares more about nearly perfect grades while taking the maximum level of class rigor possible at your school. If you don’t have that, even a 2400 SAT score and amazing extracurriculars and recommendations won’t get you in.
My D had a friend who was accepted to MIT but not to Berkeley.
