I graduated from New Haven in 1915, just a quarter of a century after my father
When Nick Carraway says he graduated from “New Haven”, he really means that he went to Yale University.
He doesn’t call it Yale because he’s just too cool to use the mainstream name. His father went there too, and it’s family legacy. It’s all part of their whole façade of being old money rather than new money. He acts casually super sophisticated and educated so that he doesn’t sound like the founder of his line was only three generations back.
