How much does the Math II curve vary by?

<p>^thread title. I'm just curious, because my math teacher who has been tutoring for the math SAT for many years now says the recent curve is probably a few points harsher than the curve present in the scoring scale of released tests and prep books. Is a -7 usually still 800 and a -14 usually a 730? (As it is in the CB Official Study Guide for Math Subject Tests)</p>
