Wow. The public school system sounds terrible. Sorry to hear that it exists.
Is this a downward trend in the math placement scores (for those applying to private school or those accepted at the private school) or is that a function of the Pandemic? If it is the latter, we can probably expect a rebound. I would have thought that with private school applicants, you would be looking at students generally in the upper quartile. Or is the upper quartile score also declining?
