There’s already self-selection taking place in the pool of kids who take the SSAT-- there are no dummies.
I know of quite a few families not needing FA and having acceptances in hand, who opted for less “intense” schools because they knew the high-SSAT schools can be real pressure-cookers, and they were seeking better study/life balance.
Hindsight is 20/20. If we could do it all over again, we would give more consideration to less uber-intense schools for both our kids.
