<p>I have encountered the following problem when I was doing my 11 SAT tests by Princeton Review... the SAT scale tables are all different!</p>
<p>I'm sure this is not an error, but why are they all scaled differently? Is it because of the level of difficulty of the tests? I found those I've done pretty much at the same level you see...</p>
<p>...and how am I supposed to know whether I have really improved on my skills? lol this sounds stupid but I really want to know whether I've improved by doing the tests in order to provide myself greater confidence.</p>
<p>They're scaled differently because in real administrations of the test, kids found them different in levels of difficulty. But if your score goes up, you are doing better.</p>
<p>Even each real SAT test uses a different scale to convert raw scores to scaled scores. The scale depends on the relative "difficulty" of that particular test, as determined by previous experimental sections etc. The point is that a 700 on one test should be comparable to a 700 on any other SAT test (and so on). Also, I would recommend getting the Blue book and taking some of those tests to get an accurate representation of your score. The first edition of the 11 SAT's by PR was actually published before CB put out their own guide book (Blue book) so how valid the tests are is questionable</p>
<p>thx very much. that's a comfort cuz my score's going up, although not rapidly.</p>
<p>i have another question actually - you know you have to divide the number if questions answered wrongly in order to get the total score in each section? what if the number is undivisible by 4? am i supposed to round down or round up? (it might not make a huge difference, buet just wanna clarify =p)</p>
<p>and what would be considered as a decent score at the ivies?</p>
<p>always round up, for example if u have 53 correct out of 55 ur raw score will be 53 - 2/4 = 52.5 ~ 53 which may increase ur score up to 10 points :) however if u have 52 correct out of 55 ur score will fall down to 51 ....</p>
