Undergraduate teaching in Berkeley is basically completed by professors, so undergraduates can get close contact with world-class cows and even Nobel Prize winners (there are 2/kloc-0 professors in the first school and 69 alumni won the Nobel Prize). Berkeley is the most comprehensive university in America. Almost all majors are in the top ten. Science, engineering and liberal arts are among the best. Business schools and law schools are also in the top ten. UCSF University and University of California, Davis were originally Berkeley's medical college and agricultural college, but now they are separated. As for the major, you need to consider it according to your own interests and specialties. If not, it is also a good choice to choose a major that is easy to find employment after graduation. Because there are high-tech companies near Berkeley, engineering, mathematics, business administration and economics are all good choices.
