DECEMBER 2008 SAT Subject Test: Math Level 2

<p>GetMeIn-I thought it was harder. I got 800s on all of my pts and 780-800 (yes, 800) on Barron’s Math 2 and I still left like 5 blank due to time restraint
I was overconfident and I guess I paid for it!</p>

<p>let’s hope it’s over-curved…</p>

<p>i did better on barron’s practice tests too</p>

<p>Dude, if it’s -8 or -9 raw = 800, I will thank the gods of math (Pythagoras, Euclid, Newton, and Leibniz) by offering sacrifices of grey matter. ;)</p>

<p>You and me both hookem. Aren’t December tests usually nicely curved, since all of the l33t people are done with their tests and applied ED? I heard that someone about the SAT I; I hope it is the same for SAT II’s.</p>

<p>^ That is quite an interesting observation. Maybe THAT’S why last month’s SAT I curve was so bad. All the smart kids took it on one day haha</p>

<p>The long distance question calls for a local thread:

<p>hey guys i just need confirmation on the weird trig function graph, when i last asked it seemed like 4pi is right, but on the updated list its written 2pi can someone plz correct that cause its causing me alarm lol. unless someone has different opinion…</p>

<p>It was 2pi dude. I had the equation stored in my calc after the test so I double checked it.</p>

<p>The period was not 4pi because the function was an absolute value of a trig identity, thus halving the period (since the function could not be negative).</p>

<p>Hey, ummm the compound interest was 3800+, not 3686. 100% sure.</p>

<p>So are we in agreement that this test will either have an average curve of -7=800 or better? Someone said they were making 800s on Barron’s and this was harder…</p>

<p>The question with 2PI, how was the question stated again?</p>

<p>And for the standard deviation, after the same number was added to all the values, the standard deviation was unchanged, correct?</p>

<p>I’m so nervous, omitted 1 and I know for sure I got at least 2 wrong.</p>

<p>One more thing, for the compounded quarterly, will I have gotten the right answer if I just did it manually? Like 1 by 1 for each quarter of a year.</p>

<p>Yeah the standard deviation stayed the same.</p>

<p>^ I think so, but that must’ve taken a helluva lot of time :(</p>

<p>lolz, you think YOU’RE nervous? I’ve got 5 omits and 1 wrong for sure. That means I can still pull an 800 (and based on the posted answers, I’m fine for now), so we’ll see.</p>

<p>Haha, just 4 times isn’t too time consuming. I think it was 4 times right?</p>

<p>I fell for #49, the probability question concerning how to choose 4 people from 16 and then 1 from that. Didn’t multiply by 4.</p>

<p>For the deep water question, do you remember the graph being in the negatives or :0?</p>

<p>^ That sucks. </p>

<p>I don’t remember. I think I graphed it and the given range was positive, and its amplitude was 8.4</p>

<p>EDIT: @$#! Why does my post always go through some cyber wormhole and pop up above the previous post??!!!</p>

<p>What was the deep water question? 8.4?</p>

<p>Yup, i believe it was 8.4 or 8.7 or something like that.</p>

<p>===================================================

<h1>The period was not 4pi because the function was an absolute value of a trig identity, thus halving the period (since the function could not be negative).</h1>

<p>even if we’ve taken the absolute value of the function, still, the period is defined as the “time” it take the function to complete one full cycle. according to the graph of the function, the distance between to similar points is 4pi, so that should have been its period. at any rate can u [Theman666] write the equation i wanna check something. or at least pm me if its an issue to write it on this site.</p>

<p>if i omitted 3 and got 3 wrong, would i still be able to pull an 800???
hope i do:(</p>

<p>i hope it too, cause I had about the same your raw is 43.25, mine about 43.5-44.25. Usual curve is -7/ -6 so it depends in our case :)</p>

<p>for the period question with absolute values im pretty sure the period doesnt get cut in half, because you can still have a negative value for x, its just that all the y values will be postive…but then again i might be wrong</p>
