<p>“What was the one with the plane intersecting the cube? The choices were I. square II. parallelogram III. triangle. It was all three, right? The fact that they put both “square” and “parallelogram” threw me off because a square is a parallelogram.”</p>
<p>I don’t remember this. D:</p>
<p>It was one of the first few questions, I think in the first 10 or 15. It asked something like which of the following shapes can be formed when a plane intersects a cube.</p>
<p>^ I got (0,z,0).</p>
<p>I forget what letter it was for #50, but the answer was 2.</p>
<p>it was b</p>
<p>and what plane intersecting a cube… i dont remember that problem at all…</p>
<p>does anyone remember getting an answer like 38751 for a geometric progression qn?</p>
<p>Oh never mind, I must be going insane. The cube problem was from the last practice test I took… haha, I’m getting all the questions mixed up.</p>
<p>I think it was B.</p>
<p>Oh good, I thought I didn’t do that problem haha.
And I don’t remember getting any 38751…</p>
<p>It was like 13870 or something for a bacterial growth problem, if that’s what you’re referring to.</p>
<p>yeah it was 13870…thanks for clarifying</p>
<p>How did you guys use matrices for the last one?
I just solved it through algebra 
ax=1+2x
0 =1+(2-a)x</p>
<p>So if a=2 no solution</p>
<p>I believe it was ax = a + 2x
ax = a + 2x
ax - 2x = a
x(a-2) = a
x = a / (a-2) Thus, if a=2, there’s no solution.</p>
<p>Matrix…
I did [A] = three different test scores the three students received
And X = x,y,z (x=score for 1st test, y=score for 2nd test, z=score for 3rd test)
and made [A]X equal to , the sum of test scores earned by each person.
So [A]X= and found X. </p>
<p>For X, I got [3 2 5]. </p>
<p>Since y=2, the answer was 2.</p>
<p>Anyone know what the probable (not min) raw score would be for an 800? I always feel confident until i get my test back and look in horror at my silly mistakes</p>
<p>I doubt the curve will be really significant, because this test wasn’t really that intricate.</p>
<p>I doubt the curve will be really significant, because a lot of the concepts tested in this administration weren’t really that complex.</p>
<p>Soooo the general consensus is that this test wasn’t too hard and the curve will be harsh?</p>
<p>I thought this was a really easy test.
There were couple of tricky ones here and there, but when I read the thread
It seemed like I got everything right however, I’m not sure about the</p>
<p>x^2 < 4</p>
<p>I thought it was (0,2) since it was the only one out of all the choices that contained values that matched the description…</p>
<p>but then I chose (-3,3)</p>
<p>:(</p>
<p>Sorry to bring this question back up, but I feel that the answer for the two intersecting lines question is “two perpendicular lines”. Let me explain, but please feel free to tell me I’m wrong. 
I’m trying to argue, just curious.</p>
<p>I can understand how it would infinitely many perpendicular lines if there was 1 line in an xyz plane. Because you can just rotate it. But wasn’t it two interesting lines? That are equidistant? Can someone explain?</p>
<p>Gloria, the general consensus is that the answer is (-3,3).</p>
