Since I don't see any particular reason you're going with TESU over any other school, do you mind sharing why TESU vs Pierpont/UMPI (or even just UMPI)? I would think for your son's current professional interest, his age, his current lack of RA credits the later would be a better option; and much more budget friendly. I would urge him to go for a BSBA/BABA over a liberal studies. He is quite young, and a business degree would have better ROI long term. Now, if he has technical aspirations then maybe the Pierpont/UMPI BAS might be another option, but since your plan doesn't include anything technical at all, so I would say go with a BABA.
