<p>So the blue book gives you your score in ranges... so how to you determine you real score?
because people around put their actual score... do they take the median or what?</p>
<p>The real score is dependent on the population that takes the test in any one sitting. It's a statistical thing. Since there's no test-taking population for a blue book practice test, there's no way to compute an actual score on the practice test. When you take the test for real, you will receive a real score (not a range of scores). The blue book score range is there to give you an idea of where your score would fall in an actual test administration.</p>
<p>Yes, this means that you can get different scores for exactly the same number of correct and incorrect answers on two different sittings. That's because your score is normalized to reflect how you did in comparison with everyone else who took the same test at the same time. Normalizing scores is how they account for different versions of the test possibly being more or less difficult than other versions. Like I said, it's a statistical thing.</p>
<p>so then for my practice tests...
if my range for something is 640-710... do i assume i'll get something around the middle?</p>
<p>The only thing you can assume from practice tests is that they make you more familiar with the format.</p>
<p>You could be pessimistic and use the low end of the range, or be optimistic and use the upper end, or be in the middle and use the average. Pick one and try to improve it as you go through the tests.</p>
<p>The blue book test questions were taken piecemeal from various SATs given in the late 90s and early 00s so there is no way to assign an "exact" score. Try the two SAT tests available as PDF files from the collegeboard; these were actual tests so you can get an exact score.</p>
<p>Do them under strict time control, no distractions.</p>
