I am impressed with how well you are thinking this through. That’s why I asked about Exeter coming off the list. There is definitely a “trust your gut” element to this process, but it only works once you have done the research. Sounds like you have done the research. So. ??
You can be type A and anti-stress at the same time.
You’ve got a great list, the schools are quite different, but each has a reason for being there. NMH seems like a bit of an outlier, curious what your thoughts are there. I ask, because adding a few higher admit rate schools is really the only thing I think you need to do. Anything that attracts you to one school is a clue to what might fit elsewhere.
Oh, I second George btw. And Emma Willard.
