Congratulations. You're brilliant. (BFHD)
Unfortunately, you couldn't have scored higher than 160 on a PSAT, in which scores range from 20-80. Even if you are a recent test taker, when PSAT has three sections, you couldn't score higher than 240. Even if you understand that the PSAT scores are scaled down by a factor of ten, you couldn't have score 121.2, as there are no fractional scores. (Oops! So much for the "brilliant" comment...)
What was the score range 35 years ago? I'm not sure I took an SAT as I dropped out in early Nov in my senior year to enlist.
