PSAT to SAT comparisons are all over the place. Math wise, I got a 720 on my first SAT, a 70 on the PSAT, and a 780 on my next SAT. I made dumb mistakes on the PSAT math section. I got a slightly lower score on the CR section (30 points lower), and I got 50 points lower on the writing section--I only missed one or maybe two on the PSAT writing and I always missed 3 or 4 on the SAT WR multiple choice. Overall, though, I got exactly.the same.score on the PSAT and my next SAT (224--2240). Weird.
