Congrats on two great acceptances! You’ll get a great education at either one.
Top companies recruit at both. Career services is strong at WM; I don’t know about Michigan, assume good though.
Have you visited? The schools have fairly different environments. WM obviously much smaller (6300 undergrads), and adjacent to the nice Colonial Williamsburg area, with a fair number of restaurants, bars, delis, pubs, etc. Very walkable from the traditional LAC-type campus. Michigan obviously much larger, with more of an urban feel, on campus and on adjacent streets, with a couple of nice streets with restaurants, etc. nearby. Students tend to live on campus longer at WM. D-1 sports at WM but truly big-time football, etc. at Michigan.
Outstanding students at both. I know WM better and students are bright, purposeful, hard-working, and very nice (notably so). I was impressed with all the Michigan gear we saw there. Greek life is very moderate–big enough if a student wants it, small enough that one can completely ignore it.
William and Mary gets the nod for weather. It’s rarely very cold and rarely for long stretches of time.
William and Mary has an outstanding economics department and business school. One might give WM the nod for a business major; Ross would probably get the nod for a business major. But I don’t think in a significant way, and that could be argued. Good luck!
