are practice SAT tests accurate?

<p>I've taken the SATs two times, with the second time receiving a score of 650/ 680/ 570 in reading/math/writing, respectively. I took a full practice test from "The Official SAT study guide" from collegeboard and it says I scored 680/800/680. I'm really doubting I can score that on an actual test. Are the practice tests an accurate assessment of how I'll really do?</p>

<p>The first three tests are actual SATs, so the answer is yes (unless you gave yourself too much time, etc.).</p>

<p>To a lesser extent, the answer is also yes for the last 7 tests, note that you get a score range as opposed to a single score for the reason that the last 7 tests were not administered.</p>
