When I took the PSAT last year, I got a 62 (which is equivalent to 620 on the SAT).

But when I took the SAT in March, it dropped to 570.

Then, when I took it again in June, I got a 700, and I didn’t even study for it.

I think it depends on the vocabulary they put on there becuase you might know all of the words on one test, but you might not know half of the words on the other.

Also, for me, some of the reading passages were more clear and interesting to follow along than the other passages.

PSAT should be easier since there is no essay portion and also is about two hours shorter than the SAT.
