The OP and his son live in Georgia, and son was accepted at Georgia Tech where he would have in-state tuition and much better weather, and he turned down GT for Northwestern?! U.S. News ranks GT as #3 in BME, Northwestern not even in the top ten. I realize USN rankings aren’t always the “final word” in college rankings, but GT is very highly regarded in BME by all relevant ranking entities, including engineering-specific ones. If given a choice between only GT or NU, I would pick GT with absolutely no hesitation.
