I think 90% of the reason for 3-2 programs is for parent benefit during the college search and selection process. They are usually not very practical, and I think the reality is that almost no one actually takes advantage. They are more of a marketing tool than an educational one. I’m not taking a shot at Colgate specifically, and maybe theirs is different, I have no specific knowledge. But lots of LAC’s have them, have kids going in either thinking they will take advantage or at least selling that story to their parents, and then the kids either don’t pursue it or drop off of the plan. A large reason is that these kids are for the most part having great experiences at their schools and don’t want to give up their senior year with the great friends they have made and the great education they are receiving.
It sounds like he is getting along really well, and the weight loss may be from healthier habits and not lack of access to food. Unless there is something you aren’t sharing (which is fine) I’m not sure why you are bringing up a transfer. It sounds like pretty normal college issues he is having. He is at a great school that outperforms their already high ranking when it comes to job placement and alumni loyalty. If he is happy I wouldn’t muddy the waters for him. It’s unlikely that a move would be even lateral when it comes to his job prospects. If he isn’t unhappy I wouldn’t walk away from Colgate.
