Jan. 22nd experimental and curve?

<p>hwuah? I understand all that gibberisih but wha?</p>

<p>what if i had M(MC),V,M(MC),M(QC),V,V,M...is it possible that the first section is experimental? it had the question with the bees in it and a question about cutting a rail into 6 pieces and one of them was a minumum of 4 inches or something like that...and i had the reading passages that were about the Memphis guy and fossils...any thoughts?</p>

<p>i had the same test as you, but those questions that your describing were on the third section.</p>

<p>the third section is experimental for you dukesoph, its on the collegeboard website</p>

<p>u really think that there'll only be three 800s on the verbal scale?
was this test generally easy or moderate or hard?
i guess if it were moderate you'd get four 800s. (last June I took the SAT once.. int'l students deemed it pretty easy; there were four 800s on the scale. At least I found
this one to be of similar difficulty.)
hmm...
by the way.. you guys are doing great! 1500+ predicted all over the place.. personally I ****ed up this test because of so many careless errors, hope mine doesn't drop from a 750 verbal cause this is already my THIRD time :(</p>

<p>puddinggirl.. what do those "a"s and "b"s represent, anyway? the probability of what?;
apart from all that jibberish, are you saying that the level of difficulty (or the score scale in other words) is predetermined?</p>

<p>a represents the right %, while b represents the wrong %</p>

<p>for example, in 78 questions verbal: if I get 60 correct, 10 incorrect, and omit 8, then my a = 60/78 = 76.9% & b = (10 + 8)/78 = 23.1%</p>

<p>yes, before you took the test, the curve is already determined. It is very accurate because CB statisticians draw simple-random-sample from the experimental sections; they often consider the "Type I" and "Type II" errors as factors, plus they use the complex randominzation equation of "normalizing" --> The level of difficulty and the curve are all predetermined before the test</p>

<p>oh. ive never seen P(a) notations for "a%" tho..</p>
