Re: who went to Berkeley?
Berkeley admission evaluation favors admission factors such as a rigorous of HS curriculum (number of UC-approved honors/AP/IB/CC courses completed), excellent weighted and unweighted GPA, and demonstrated leadership abilities. You are also compared to your peers, meaning your academic and extracurricular achievements are viewed in context of students in your HS who applied to the UCs this year and up to 3 years prior.
Berkeley is general achievement oriented (academic or extracurricular), meaning admissions is willing to overlook bad grades/test scores when excellent extracurriculars and/or horrible hardships are in the equation. Berkeley is especially interested in students who will take advantage of what Berkeley has to offer and become the engine of social change.
