What "safety" schools are out there in the Mid Atlantic/New England area that I should consider?

Lawrence Academy, in MA, has a 50% acceptance rate.

Agreed, what are you looking for? If you have stats that could get into PEA or PA you are not going to be happy at a 50%/60% acceptance rate school. IMO. Unless you are a very very chill kid who doesn’t care about how rigorous your peers or classes are.

Let us know something about your stats and what you want in a school. Then come up with a list that has some reaches, matches, safeties.

Are you a 7th grader with time to do this?
