I’m sorry but this is extremely bad advice to give to a rising college freshman. It has often been said on CC that dream schools become nightmare schools when they require you to take on student loans exceeding the subsidized limit (>$27k). Do not do AFROTC unless you seriously want to serve in the military.
GT is hands down the better school for computer science or engineering and an all round better choice if ND requires any debt at all. ND has some rabid boosters whose loyalty is endearing only if they are willing to pay your tuition themselves. Otherwise, GT is the only reasonable choice.
