Tufts is ranked 27th nationally while UPenn ranks 8th according to USNews. I also personally never heard of Tufts until now but that of course doesn’t mean it isn’t a great place to be. I would say that UPenn is confused with Penn State because Penn State used to be a football star but confusions aren’t as common now and are dying down as UPenn implements its Compact 2020 plan to spread its influence and name across the globe.
