@Commiserating, Proximity to home is a double edged sword. Being too close can inhibit a student, especially an introverted one, from integrating into the collegiate community. Knowing you’re not isolated is important though and there are many ways to get to that point. First and foremost, have her go to the full orientation program. She’ll develop friendships right out of the gate. Live in a dorm with other students who are studying engineering. It’s hard to live with business majors because the pressure to party (not that there’s anything wrong with that, it just needs to be self regulated) is too incessant, due to the far softer work load. If possible, she could go somewhere that a classmate or two are going?
As for suggestions that are far from home, you started with Michigan and Purdue in your very first post. Last time I checked, they’re pretty far from the great country of Texas. :))
Lastly, it’s really hard to know how “smart” most kids are these days based on the rampant grade inflation and teaching to the AP test that’s happening out there. I think the level is actually very high, but 4.0 and 5s on APs aren’t actually super predictive of success or ease with the workload, especially in engineering. I’m not saying that to demean your daughter in any way, but as a warning not to be complacent. Make sure that she hunts down old tests and the syllabi for any classes she wants to use AP credit for so she can review and know with certainty if it’s a good idea to skip.
My son’s Calc III class is an anecdote to support that previous paragraph. It was an invitation only honors section for students who scored 5 on the Calc BC AP test, starting first term freshman year in Calc III. On their first exam, there were plenty of scores in the 30s. None of them were dummies. They just likely overestimated their readiness and need for study based on their previous successes. Engineering is a different game, even for the brightest.
Good luck.
P.S. It’s VERY important to visit a few “Small” schools to get an idea what they will really be like. Small schools, in general, don’t feel that small. Certainly Case didn’t. Find a school close to home. Walk around. Go into the classrooms. Let her see for her self if she hasn’t so she’s forming her opinion based on something more than a numeric.
