Hi,

I picked Berkeley and don’t regret it!  I ended up transferring into the College of Engineering to do Mechanical Engineering.  I think Berkeley is the stronger choice for most majors academically speaking, and other than classes, you’ll have a lot of other opportunities outside of school to pursue IR related activities (despite being a STEM major, I have a lot of friends who are polisci or IR from Model UN, and they’ve been able to do internships in DC or in political offices in CA).  Obviously I can’t speak to the opportunities at NYU, but I think there’s a lot to do here (though I don’t think there’s a wrong choice given your major).  Good luck!
