Maybe they're trying to strategize on SAT Prep book marketing /s.

Jokes aside, SAT score is not a good indicator of "success" in terms of salary at least in my personal circle. Some of my friends who got perfect scores on their SATs are all at sub-standard jobs, getting paid significantly less than the average salary. Of course, this is purely based on personal anecdote but attending top-tier schools seem to have a stronger correlation.
