When I took the PSAT it was when it was still out of 1600, but when I took the SAT it was the first year that it was out of 2400.
Middlepath: Did you have a very long gap between the two? Because the PSAT switched to 2400 a number of years before the SAT. I personally took the PSAT twice, in 10th grade and 11th grade, both out of 2400. Then in 12th grade, I took the SAT and it was still out of 1600 – it switched a few years later.
