SAT Scoring

<p>I have the Official SAT Study Guide by College Board and my scores seem to be improving but I don't want to get my hopes up. How close is the scoring in the College Board book to the actual scoring on the SAT test?</p>

<p>I was also wondering what the advantages of omitting a question you are unsure of are over just guessing.</p>

<p>Thanks for your help!</p>
