As you mentioned Wall Street being your current goal – and i don’t mean to use “current” to patronize you, only to highlight that some kids change their minds and majors at some point – these seem to be the top target schools. Check wall street oasis’s site for confirmation or correction:
Tier 1: Harvard, Yale, Princeton, Wharton
Tier 2: Penn (non-Wharton), Stanford, Cornell, Dartmouth, NYU Stern, Columbia, MIT
Tier 3: UChicago (may become higher as B school gains footing), Northwestern, Duke, Brown
Tier 4(?): Georgetown, Notre Dame, Vanderbilt, maybe CMU, Emory, WUSTL, USC, BC, Michigan, Berkeley, UVA, UCLA…
Maybe UChicago is Tier 2 now, and I don’t know how much of a recruiting/interest difference there is between these Wall Street placement tiers, but I imagine kids at any of the above schools – provided they make good use of their schools’ career offices, get strong grades, are personable and somewhat outgoing, etc. – have an easier time drawing interest from Wall Street than the rest of the world.
But where do the top LACs fit in? That’s what I wonder. I’m sure Williams, Amherst, Bowdoin, Middlebury and some others have their own long-established WS ties. But i don’t know how the level of recruitment compares to the university tiers mentioned above.
