In the 80’s we had SAT prep, but nobody bothered to prep for the PSAT (we knew what it was, and knew it was now to qualify for National Merit, but it just wasn’t something you prepped for). That said, I find it amusing seeing the posts about the changes to the scoring, both with the SAT going back to a 1600 point test, and the PSAT score vs. NM selection index. I’ve seen so many posts claiming the score has always been the same as the selection index, but that’s just not true. in the 80’s the PSAT had 2 sections worth 20-80 points each, for a total of 160 (add a trailing 10 to get your projected SAT score). The selection index was simply double the English score, plus the Math score. If you look carefully at the way the new selection index is calculated, it’s exactly the same. You total English score is the Reading and Writing subscores while the Math score is the math subscore doubled. The Selection index (double all 3 scores) is the same as the 1980’s selection index - double the English score (2 reading + 2 writing), plus the math score (which was already doubled). Since the score range of the test of 10th and 11th graders is 4 points lower per test, the selection index should be about 12 points lower.
