January 2011 - Math Level 2

<p>oh yeah i think i put B (I only) for that one</p>

<p>ugh, I put I and III just when the proctor said to put pencils down…</p>

<p>was ‘n’ the answer to the (4a+4b+4c+4e)/16 = n question?</p>

<p>Yes, it was ‘n’ :)</p>

<p>good lol, so there is hope yet for an 800…i’m at a -6 already T-T</p>

<p>I omitted 5 and got 2 wrong, so my chances for 800 are pretty slim :confused: Good luck to you though ;)</p>

<p>Damn. I factored out 1/4 instead of 4.</p>

<p>It was my first Math Level 2 test, and I thought it was pretty easy (compared to Barron’s - there were no ellipses, hyperbolas, limits, etc.). However, some of the questions were, in my opinion, kind of tricky, or just easy to the point where making a mistake was so inevitable :P</p>

<p>These are just a few questions at the top of my head. I’m not sure if all are right:</p>

<p>Gloves question, I got 4.
Probability of picking out an even number from (1,2,3,4,5,6,7,8,9) = 1/6
Surface area of cube = 54x^3, find volume = 27x^3, from what I remember.
Some question with G(X), I think I got G(X) = 2 or 3, forgot. Most likely 2.
Question with all points 2 units away from line, I put they form a cylinder.
Question with triangle that has one side extended, find cos(x), I got -0.8 or something like that.
Question with parabola, prove why there are no solutions, I got because vertex is above x-axis and the parabola opens up.
There was a question where I think I put the answer as F(X)=X^3+Y^3.
There was also a question with what possible values of ‘n’ for F(F(X)). I put 1 and -1.</p>

<p>Anyways, that’s all I can remember now :P</p>

<p>What about the one with a^x then it asked what is f(m times n) or something like that. I remember putting f(m+n) since a^(m+n) = a^(m) times a^(n)</p>

<p>^Correct. Thats what I got as well.</p>

<p>Yes, that is correct as well :)</p>

<p>Do any of you guys have experience with the Math IIC? Do you think the curve for this test will be lenient?</p>

<p>for one i think i remember putting x^2 + y^2 < square root of 13</p>

<p>I remember that answer, but don’t remember the question. You have any idea what the question is?</p>

<p>yeah the question gave two sets of points such as (0,0) and (2,3) or something like that and then it asked under which circumstances would points (x,y) have a distance less than the distance between (0,0) and (2,3)</p>

<p>It’s typically -6 raw for an 800.</p>

<p>& also, did anyone have 3 Bs in a row at the end? like 48: B 49: B 50: B</p>

<p>Yeah, I think that answer is right ;)</p>

<p>Totally forgot about last 3 questions - didn’t have time for 50. I remember I left the question with the 1,250 something tripling in 30 years because the answer I got was not in the multiple choice.</p>

<p>^yes, my last three were all B.</p>

<p>@austraboy: which question was the F(x) = x^3 + y^3 the answer to?</p>

<p>haha yayyy i’m aiming for a 750+…and so far only one omitted and none wrong!</p>

<p>I totally forgot the question, I just remember that you had to consider that they could be negative.</p>

<p>I also remember a easy question with polar coordinates, I think I put E. There was also another question that said ‘s’ and ‘t’ were the roots of an equation, which equation has the roots ‘s+1’ and ‘t+1’? I’m not sure but I think I put B or C.</p>

<p>Also, about the question with X^2+Y^2<Rad(13). I was just thinking, shouldn’t it just plainly be X^2+Y^2<13? I totally forgot what I put.</p>
