Only thing I’d probably try to factor in would be where does the student think s/he wants to live when they really grow up. If the student grew up in, say, Georgia or elsewhere in the mid- to deep south and has lots of close family in that area, I’m not sure paying 2x more to go to school way out in LA would be warranted.
I think UGA’s academics are just fine. Sure, UCLA is regarded as a “public Ivy,” and certainly is a bigger academic “brand name” than Georgia, but for an undergraduate poli sci degree, just not sure the bump in cachet one gets from UCLA is that substantial. Plus, Athens just seems like a fun place to spend 4 years – big sports, big school spirit, great local music scene, and lots of brand recognition in its own right.
