Interesting SAT/IQ conversion chart.
Out of curiosity, when was this chart published? Also, what’s the source—there’s a lot of precision—perhaps false precision—in carrying the estimates out to a couple of decimal points.
I ask about “when” because I’ve heard it stated that current SAT scoring is some 50 + points more generous than the scoring of a generation ago. “It was harder in the old days!”
maybe you can find out more here——SAT to IQ conversion

I recall all too well my prep back in the early 70s, and I helped my daughter prep in the early 2000s. I probably took the test 6 times total, once in sophomore year, twice junior year, and three times senior year. Since college apps have been sped up in the intervening time, so that you apply and receive a decision sooner, my daughter took it 5 times total, mostly in her junior year.
The math in particular is much easier overall, I think they have just moved calculus to the AP altogether. Verbal has I think fewer problems to a section and they are not as complex, particularly the reading comprehension. There's a "luck of the draw" factor because there are 5 sections, so you may have more verbal (which I prayed for). Also, one section is usually a "test drive" of new problems and doesn't count towards your score. My best score was the test where I got 3 verbal and 1 of the math sections was new problems and didn't count. :-)
