What should my D do?

^^^ Fancy that!! What would she like to do?

That is the only answer, really.

I would remind the young woman and her family that true learning isn’t a race, or a set of “check-the-boxes” - if she is turning down a chance to excel for a chance to get out sooner, she would probably be making a mistake. (What I mean is, is she simply meeting the degree requirements, or looking like a student graduate schools and employers will say “wow” about?)
