<p>The CB tests show that a raw score of 43 to 50 = 800. Does it change? Also, it looks like you only loose 10 points for 1 error, very forgiving compared to the SAT 1.</p>
<p>Is it possible that CB will scale or equate the raw score needed for an 800 if way too many kids do well on a particular version of the test? i.e to get their bell curve do they end up changing the raw score you need for a certain score vs their published scales?</p>
<p>Hope I put forth my question clearly???</p>
<p>The test is not curved in the sense that they look at how everyone does and scales it. Each question, instead, is tried out in other exams, and the percentages that got each question right in the sample are taken. The questions are then rated easy->hard. The "curve" is determined by how many "hard", "medium", and "easy" questions there were on the test. So if a test is harder, in general, than a previous one, it'll be more forgiving than, say, an easier one. </p>
<p>Hope this helps...</p>
<p>Thanks Ashraf Eassa. After I made this post I went back to the CB Math Test book and noticed that the process is exactly like you indicated. The 1st test was easier (had fewer of the hard quesitons) so it was less forgiving than the 2nd test in the same book (which had more med & hard questions).</p>
<p>i.e with the same raw score you could get 20 points lower on the easy test.</p>
