@simba9 ,“never had to take differential equations.” Maybe that is school dependent? My son had to take it at VT and I just looked at the undergraduate checklist on the ISE website and it is still a requirement to take differential equations to get a B.S. in Industrial and Systems Engineering there…
Chardo, Your son sounds like a great kid and very focused. He already has a lot of math and engineering under his belt, which is great. From what you are describing , it does sound like he would thrive at Georgia Tech in engineering (if he also likes the school in general). But, it is your money and nobody here is going to be able to tell you how to spend it. Is there an accredited IE program in your state that would be cheaper that could be considered? Good luck.
