What’s the magic number of schools to apply to?

@HappyTimes2001 I never said kids won’t be happy at their second or third choice BS, my own kid applied to 4 and could likely have been happy at any of them. I did say kids are unlikely to be happy at a school they consider ‘safety school’, because that implies belief they are too good for the school from the start. That’s just what I have seen and read, though I have no doubt there are exceptions. Hence my belief you should only apply to schools you love and would be happy to enroll in.
