Very well said, and I agree wholeheartedly.
In this situation, the “fit” issue is, in my view, about the fact that Bentley is overwhelmingly focused on business. Thus, a student needs to be sure that business is what they want. If they discover after beginning classes that business is not what they want, then some significant problems could ensue. In other words, Bentley is a tight “fit” not a loose fit. If something changes, the fit could become quite unpleasant.
One question OP might consider is “how easy would it be to transfer from Bentley to BC, or some other school, if the student determines that majoring in business is not where the future lies? And what would be the total financial cost of transferring?”
