Convince me to repeat 9th grade

Where is @CaliMex when you need her to dispute admission % claims?

Ok, I jest, I jest.

There are three totally incorrect statements in that quote:
Firstly, Exeter and Andover are not the most selective BS. Lowest acceptance rate goes to Thatcher and Groton.
Secondly, there is, quite literally, no such thing as “necessary SSAT score.” I know kids at Andover who scored abysmally on the SSAT. ABYSMALLY!
Thirdly, your mom is not getting good advice. It’s basically people who don’t really know, don’t know what they don’t know. Those schools are absolutely “famous” but definitely not “unmatched.”

Finally, the best school is the one at which you, the individual you, can succeed and be happy. That is not the same for every kid and cannot be chosen simply on the basis of academic rigor. I personally know schools that give Andover a run for “most rigorous.”
