Let us know how it turns out for her. You may be surprised. If she applied to 17 schools, they can’t all be top 10 (or Ivies).
My guess is that she doesn’t have parents or advisors who introduced her to great schools that aren’t so hard to get into. If she strikes out this year, she has next year to figure it out and she goes to school older, wiser, and more experienced. I’m actually more surprised by people who pay massive amounts of money to send their kids to mediocre LACs. This kid is saying if I go to college, I want to go to an excellent college/university and one that challenges me. She may not have a nuanced or accurate view of excellence yet, but it’s not a bad goal.
