<p>How did everyone find the test?
I thought it was much harder than I expected it to be, especially since the tests on the College Board textbook were really easy (790 on both). I'd be lucky to get 700 on this one; I found at least 5 or 6 questions that troubled me (i.e. matrices). I'm also international, so a lot of the American phrasing of questions baffled me. Hopefully the curve is a little more lenient than it usually is.</p>
<p>(I think I had the 4KCB1 test booklet).</p>
<p>The answer to that one was a=-b and c=0. I don’t really know how matrices work, but I created two matrices in my calculator that fulfilled the conditions in the answer choices and then matched the one that gave me the matrix with four 0s.</p>
<p>Yeah I have no idea how matrices work, so I left out that question.
Do you know what the answer to questions 27, 38 & 50 were?</p>
<ol>
<li>Find the maximum value for the zero of a function f(x)? (can’t remember what the actual function was).</li>
<li>If (x-1) is a root of 2x³+3x²+2kx+1, what is k?</li>
<li>The child doses for two different ages are equal. What is the greatest of the two ages?</li>
</ol>
<p>K is 2. I forget what my answer was for the dose question, but I remember solving it by graphing both equations to see where the doses intersected.</p>
<p>For 27 I got 1.53 for the max zero</p>
<p>The maximum zero does not exist. If 3 is the minimum y value of the function, then the y value can never be zero, therefore there are no real zeros</p>
<p>Lol wrong question! Yes I got 1.53 also, I was thinking of a different one</p>
<p>What was the answer to the question with the chord on the circle?</p>
<p>Sqrt 3</p>
<p>Damn, I already know that I’ve got 27 and 38 wrong.
What score do you think would be considered to be good for ivy league colleges? 750+?
And do you guys think the curve would be more lenient?</p>
<p>The chord on the circle one was not sqrt 3, it was 2.</p>
<p>The triangle connecting the chord and the diameter had a leg of 1 and a hypotenuse of 2. The other leg was the distance between the chord and the diameter, which was sqrt 3.</p>
<p>Yeah it was definitely square root 3. Radius (hypotenuse) was 2 and half of the chord was 1. so square root (2 squared - 1 squared) = square root 3.</p>
<p>What was the answer to 50, I put 12.</p>
<p>My prediction for the curve matches the curve in my College Board textbook.
I find it strange how the curve in the College Board textbook is so much more lenient than curves we find on Sparknotes, Barron’s & Princeton Review, but I trust it the most considering they know more about their own tests than anyone else.</p>
<p>50 - 800
49 - 800
48 - 790
47 - 790
46 - 780
45 - 770
44 - 760
43 - 750
42 - 740
41 - 730
40 - 730
39 - 720
38 - 710
37 - 700
36 - 700</p>
<p>I put 10. I found a quadratic equation and got something like 9.77, but I wasn’t sure at all.</p>
<p>For 50, I got 12 as well.</p>
<p>What was the question for 50?</p>
<p>Its the one with the 2 equations about the medicine for children and adults</p>
<p>what about that weird median question?</p>
