You already have or you can gain enough insight yourself to answer those questions. I mean, you supplied essays to gain entry and presumably have also visited these schools. And you saw and/or have accessed enough media about them to have some clues already.
So… What is YOUR sense of your future at both? What did you glean about yourself in terms of your ability to achieve your goals and to do so with distinction on their campuses? NO ONE but you can even start answering these
questions nor will anyone but YOU be responsibe for delivering on these ideas and plans.
It should be apparent that there is no magic formula. Here’s why if I were to extend your hierarchical and popular rankings-driven logic to a possible conclusion. If that were reasonable then everyone at Stanford, the USN&WR top university in the US, would be “all set” simply by graduating “because” they attended Stanford. So where does this line of reasoning belying you questions take you? It’s a false, misleading and meaningless approach to assessing and judging colleges for your personal, future aspirations.
Moving alomg, BU and Colgate are obviously very different in what they are, what they do, who they serve, where they are and, for all I know where they are going. What do you know about about their curricular and extracurricular offerings? I hope you have asked the admissions offices and through them the schools’ various departments for specific answers to your particular interests. When you have done the legwork ask yourself the question: Who are you and where is YOUR fit. No one else, and certainly no one on this forum, would have a clue.
Good luck with your efforts!
