As someone who has provided advices to various seniors in the past for college admission, your perception of “was this the right school (financially, socially, academically, etc) for my S/D?” is not uncommon. The truth is, there are multiple schools that “fit” single student’s character and desires. I would now move on from wondering about this issue and focus instead on the career options for your S. Yes, it is early that he only finished the first semester of the college, but I have seen too many college students who never think about future until their senior year and realize that there are so many things that they should’ve done. It is, in my opinion, the job of parents to make sure that your child is doing everything that is needed. One such thing is to make sure that he gets to explore his interests widely and builds a long relationship with at least two professors, preferably in different areas.
