Frankly the difference between Babson and Bentley is negligible in terms of career potential. If we’re talking a UMass vs (Babson or Bentley) I’d suggest the either of the latter schools purely because of the networking opportunities. It really comes down to your interpersonal skills in the long run. I graduated from Babson and I’m currently 10 years into my career. Sure it’s great to connect with a fellow Babson alum - the networking opportunities have helped me throughout my career - but I’ve worked alongside graduates of a variety of colleges. The thing that stands out is that individual was charamastic and a good “people person”.
You focus should be on which school environment is more aligned with your interests. Putting aside academics, the schools are very different in size. That will play a significant part in your college experience. Don’t discount it.
