<p>Are the chart and formula for scoring the test accurate for all tests or just the diagnostic. Specifically, I'm talking about the 2009 version.</p>
<p>The chart and formula is accurate compared to the Princeton Review SAT Math 1 and 2 and the College Board SAT Subject Test book. I hear that if you get a low 700 on the Barrons, then chances are you will get an 800 or high 700 on the real test. The Barron's is much harder than the real test.</p>
<p>I got a 540 on Barron's Diagnostic and then a 710 on the real thing with no prep.</p>
<p>I got a 650 on that test, but it felt weird cause I missed a lot of questions.</p>
<p>Barron's math tests are historically more difficult than the real SAT Subject tests, but their chart on the diagnostic is probably the same for the rest of their tests.</p>
<p>Another data point: 700 on the diagnostic/1 practice test and 760 in January.</p>
<p>The formula in the barron's book is accurate. I believe it's 800 - 10(44 - raw score). </p>
<p>In terms of difficulty, I got 700ish on the diagnostic and an 800 on the real thing.</p>
<p>don worry abt ultra low scores on barrons test...i had i guess 650ish on diagnostic test but a 800 on real thing...so chill and keep ur head on test day!!!</p>
