May 2013 - Mathematics Level 2

<p>omitted 5 and missed 2!! I hope the curve is a bit lenient or buh-bye 800… :(</p>

<p>Did you guys remember something like the reciprocal & I was between 2x/3 or x/3</p>

<p>I got x/3… and I omitted 8 :frowning: im hoping i only got 2-3 wrong so i can get a 750+ :frowning: does anyone have any idea what the curve would be for this test?</p>

<p>@smarty1201 it’s x/3 use the comdom feature on it 89 for 1/(1+x)(2+x)</p>

<p>Omitted three. I HOPE I didn’t miss any. Hoping for a 800 :)</p>

<p>In my opinion, this test is just as hard as barrons.</p>

<p>Yes, I think so too. Some of those questions I had never even seen before and I had done like 16 practice tests… I hope the curve is forgiving. I really want a 800 :frowning: My raw score is 42.5 (based on the discussions here) :/</p>

<p>Hey guys, this was my first time taking an SAT subject test, and i was wondering if it’s better to skip questions or guess on them? </p>

<p>I only skipped two but I was unsure about maybe 7 and i guessed on them. Should I have omitted more than guessing?</p>

<p>let me know, thanks!</p>

<p>Did you guys remember something with the volume & the answer was 48m^3 ,36m^3, 12m^3</p>

<p>@Smarty1201
Wasn’t the question like m, l=3m, h=4l? Something like that…I put 36m^3.</p>

<p>Do you guys remember something with a f(x) = x^2 as an answer??</p>

<p>@Smarty1201
Something like f(x)= |f(x)|</p>

<p>Yeah, I remember putting in 2 answers as 36m^3 and x^2</p>

<p>For f(x) = |x| I think I might have put all real numbers? But then again… I might be thinking about the practice problems I did in my workbook XD someone tell me if in right! Haha</p>

<p>That wouldn’t work for negative numbers.
For instance, |-2| = 2, which isn’t the same as f(x) = |x|.</p>

<p>^ what were the choices? Was “all real numbers” one of the choices? Because it was then I probably put that :/</p>

<p>The answer was x^2.</p>

<p>Does anyone know the answer to the one " which assures y = the square of an integer"??</p>

<p>Ha, no clue. The answers were like
x-y=n^2
x+y=n^2
and stuff like that.</p>

<p>I put (x + y)/2 = n^2</p>

<p>Because x = n^2 and y = n^2 so x + y = 2n^2 and divide that by 2 you get n^2</p>

<p>The answer was y/x = n^2 for sure. We end up with y = x*n^2, and since x is a perfect square, then y is the product of 2 perfect squares, which is a perfect square.</p>

<p>If we have (x+y)/2 = n^2, we end up with y = 2n^2 - x, which isn’t necessarily a perfect square. (e.g. n = 3, x = 2^2, then y = 2<em>3</em>3 - 4 = 14, not a perfect square)</p>
