@younghoss, no problem with your thinking on what to do if joy of learning is the object. But, if employment is the object, the question is whether she can optimize her future path going forward by what she chooses to do. If she knows what she wants to do and has taken the right course for it, I agree with your response. However, depending upon her situation, a few courses could substantially improve her marketability. Perhaps more importantly, many kids her age do really know what area they want to work in (and there is nothing wrong with that). But, one could remedy that a bit with some internships, which might be easiest to do as part of a college curriculum. If so, the suggestions of @brooklynlydia and others make sense to me.
I used to tell my kids “Life is not a race.”
My son did slow grad school down a bit (had a surgery but probably slowed the pace a bit) and was able to define and create a tech company, recruit one of his classmates, raise several million $$ in VC money, and get started before he finished (though that last quarter was a killer). Not saying the OP’s D is going to start her own company, but she may be able to better define what she wants to do and build skills that will help her before she leaves school.
