a major question on Math 2 scores

<p>Hey, so I'm taking the Math II Exam this saturday. I bought the Official SAT Subject Tests in Math Levels 1 and 2. I took the two practice tests in it for Math 2 -- and I received a 740 and 630. How can there be such a huge and discrepancy and which test is accurate? The first one or the second one?</p>

<p>Neither is accurate, but I'd say the one from 1995 (43/50 = 800 curve) is more accurate.</p>
