<p>Ugh. I hate statistics/probability. I’m guessing that my score is going to fall in the mid 600 range. >_< Should have studied more. I’ll probably retake it in December. This time with some solid Barron’s and some help from my math teacher.</p>
<p>A shortcut on #50:
the small cone is similar (think similar triangles) to the original big one;
if k is a coefficient of proportionality, then k^3=1/2 (since v=(1/2)V), so
h=(k)H
h=(1/2)^(1/3) 6
h=4.8</p>

<p>Does anyone remember the (a^3)^2 = 123.31 or something question? None of the answers, as I recollect now, seem to be correct. .__.</p>
<p>It was 123.1 in the equation.</p>
<p>The (a^3)^2 question worked out an answer choice for me…</p>
<p>6th root of 123.1 = 2.2??</p>
<p>Something like that; I don’t remember the exact number.</p>
<p>Yeah that was kind of a weird question. It seemed very easy but when i put it on my calculator nothing seemed to work out.</p>
<p>Thats what happens when I don’t know how to take a 6th root on a TI-89 lol.</p>
<p>You could
solve((x^3)^2=…,x) instead.</p>
<p>for the roots question - did the question say that it was a quadratic?</p>
<p>If I learned material from a Barron’s book, how would I find this test?</p>
<p>Barrons, Kaplan, PR, all have mistakes.
Barrons is the worst one,a lot of mistakes. It’s not a good book.</p>
<p>CB’s offiicial is fine, but it’s too easy.</p>
<p>Guys, I think this test was impossibly difficult.
What do you think will be the curve?
Have any of you taken the June SAT2 for Math2?</p>
<p>In June, I got 740 omitting 7 and several wrong.
Since this test, according to me, was harder, the curve will be more generous??</p>
<p>I need to cancel if the score’s going to be lower. I omitted 7 in this one as well.</p>
<p>I took last June’s MATH IIC, and i thought this was way easier (but still really really hard). I can’t believe college board lied to me =.=!!! I thought the blue book that I spent 20 bucks buying (and with only 2 practice tests in there) indicated the tests’ real difficulties.</p>
<p>It was definitely hard but I can’t compare with other real tests. I too thought that the official CB book was indicative of the difficulty, but both the official tests and Sparknotes tests were easier than this test. It was almost like Barron’s which is supposed to be way harder than the real one!</p>
<p>sigh.
when you take something to the 6th root, you’re actually just taking it to the power of 1/6
so 123.xx ^(1/6) = 2.2~</p>
<p>I took this in June, it was actually the same as June. In June, there was plenty of Pre-Cal. On this one there were no really specific pre-cal questions. Although, most of it it was math put into a confusing form, so in that sense it was a little harder. Overall though the difficulty was about the same, if CB is nice; maybe the curve will be more lenient.</p>
<p>Or you could also take sqrt of 123.1, then do cube root, or the other way around for that matter…there were many ways you could do it.</p>
<p>if i have a raw of 43.75, will they round it to 44? this sucks if the cutoff is 44+ for 800.</p>
