The old PSAT was very similar to the old SAT but shorter I think, though I'm guessing that you later took the old SAT in order to apply to college, assuming you didn't take the ACT instead, which was less popular and more academic in nature. If you scored like 620+ on the old SAT verbal, it's probably consistent with the antonyms score. And antonyms performance does seem to drop off with age after a certain point, so I doubt your score was inflated relative to what you'd have gotten when younger. All of the various SAT V item types seemed to be heavily intercorrelated, and antonyms were by far the best item type in terms of item efficiency (IIRC how much information can be obtained about an examinee per item, but I could be mistaken). The analogies are my favorite, but I'm biased since I seem to be better at the analogies lol. Though the analogies do seem to derive their difficulty from something other than vocab difficulty, so hopefully they're more of a reasoning test despite the fact that some items do use hard vocab.
Man, it sucks how crappy they made testing since the old SAT was discontinued in 1994. It was definitely driven by political pressure, and I think it had the opposite effect than the revisions were purportedly intended to bring about, as the old SAT depended less on quality of schooling due to testing very little specific academic knowledge.
