<p>On the SAT book, I saw some scales that said recentered. Does that mean that the curve has been used before on that same test given earlier ago but now the Collegeboard make some changes to it? For example, say 59 was an 800 on the previous test. Now, they use the same test and a 59 would be a 780?</p>
<p>the scales were recentered in 1995. scores from before 1995 are supposed to be equivalent the same score now +10-30 pts.</p>
