Self-study
Hi, out of curiosity I'm wondering how the score equivalent for full tests is determined from sections. For example, I took LR sections from PT 122 and got -1 and -0 on the sections, with PrepTest equivalent scores of 172 and 174, respectively. Wondering why, based on numbers alone, my -0 section wouldn't be a 180 equivalent, for example. Same with why the -1 section wouldn't be higher. Is it because it's an older test with relatively less difficulty than more current ones? TYIA for any insight!

Hey there! The Preptest Equivalent estimates the most likely score for someone who performs the way you did on that section. It doesn't just look at how many questions you got right or wrong—it also considers the difficulty of each question. Getting hard questions right signals a higher score, while missing easy ones signals a lower score.
A perfect score may return a 174 rather than 180 because many test-takers across a range of scores (172–180) would also ace those same questions. Since there are far more people scoring in the 170s than at 180, the model returns 174 as the most probable score.
I hope this helps clear things up!
