Unfortunately I can only visit one of them because the other two are on the other side of the country. I really like that they have a strong emphasis on the sciences and they do not distort it by forcefully injecting too much liberal arts into the mix. They also have many opportunities for internships. And most importantly, all four of them are strong in all the sciences, not just one. Therefore, I have the luxury to experiment and ultimately decide which field of science I like the most, a decision that I have yet to make.
The four schools are MIT, CalTech, Stanford and UCB by the way.
