I would highly encourage USC over Emory, definitely worth the extra penny, since the connections and reputation of USC is much greater and better than Emory. I have lived my entire life without hearing of Emory’s name, but have heard of USC my entire life. Then again, this is your son’s choice and if he also has no idea what major he is going to do, then maybe it is best he tries to figure that out before making a decision between schools like this - maybe even take a semester off to think about it.
