三个学校很不一样

大多会选Duke，名气大，但cs相对其他专业较弱

UCLA，州内学费，近，math/cs都不错，but it is a big pond.

W对准备读PhD的学生是好选择，math好，cs在LAC中算好的。到网站上看他们现在有多少cs faculty： W lists 13 CS faculty, which is impressive, given that HMC only lists 14. Note that the majority of CS faculty at W are assistant professors (at least two on leave), which means that they have recently expanded their CS faculty in response to the increasing demand (this is a good thing, reflecting the administrators' willingess to cater to students' need).
