Re: #21
UCB does not weed out engineering majors by GPA, as long as it is above 2.0. The schools that weed out engineering majors would be those like Purdue, Wisconsin, Texas A&M, etc. that have a first year pre engineering program after which students compete by GPA (and sometimes essays) to get into their majors.
UCB does have lots of aspiring pre-meds, but probably only about a quarter of them earn grades high enough that medical school admission is possible (and then they also need a high MCAT score, pre-med extracurriculars, etc.).
