<p>I recently bought the Kaplan PSAT/NMSQT Premier 2012 study guide, and took the diagnostic test. I graded it, and got my scores, but can’t figure out how to grade it, to find out what my index score is. It also doesn’t tell me how to find my index score, just based on my scores in each sub-section, what I should study to improve it. Does anyone know how to calculate the scores? Any help is appreciated…</p>
<p>It sounds as if you have your raw scores for each section, right?</p>
<p>In that case, you’ll need to flip to the back of the Kaplan book to find the score conversion charts. </p>
<p>It was a silly decision on behalf of Kaplan not to stick a copy of the scoring chart right after each test, </p>
<p>How’s the Kaplan book? Is it useful? I purchased the Gruber book for the psat. Too bad there isn’t any way to get an official practice test or something. I hear they discontinued the $3 for a test policy. :/</p>
<p>It is quite useful. The writing portion of the PSAT/SAT used to be my weak point, but with the help of Kaplan, I’m doing much better. </p>

<p>Gruber’s is an excellent book for the math portion. The writing section on the Gruber’s book feels as if it was thrown in at the last second - it’s way too long and not useful at all. I hate how the Gruber book dedicates dozens of pages to explaining numerous grammatical terms that you don’t need to know.
