A 700 or higher on the math section is good enough for a scholarship and/or admission to a very selective college, but 500 is the average score. The average engineering major, for example, scores just a little bit above average (in the 500’s) on the SAT math portion. If you don’t believe me, check here:

IOW, the SAT may be a good measuring tool indicating potential success in college, but it’s not the end-all. Employers don’t care whether you’ve scored high on the SAT. The degree is what matters.
The context of my post in the Twitter thread was "For companies looking for super-smart people".
At MIT, a 750 SAT Math score puts you at just the 25th percentile.
