<p>Honestly, I think the PSAT is harder to get a perfect on, less forgiving. I got in the mid 230s with my PSAT and a 2400. There are a lot of similiarities, but one of the marked differences is the presence of the essay section on the SAT. I relied solely on the barron’s 3500 word list and both times I took the SAT, I didn’t get any vocab questions wrong. It is exhaustive and time consuming, but not that bad if you are fast and already know 95% of the words. The errors on SAT W are more tricky than those on the PSAT W, so you’ll need some more practice. Memorize commonly-missed constructions (I think they can be found in Barron’s 2400); for example, “between you and ME, NOT between you and I” and commonly made errors (lie/lay/laid, etc)Honestly, you should be fine for math (750+) if you’re decent at math, the rest comes down to how careful of a test-taker you are. CR is harder, because I think they choose more difficult passages, and some of the last questions can be really nuanced. But there is always a bit of wiggle space with the curve.</p>
