December 2010 International Math

<p>suree? bc there were 10 numbers … i am seriously ■■■■■■■■ i have no idea how i made these careless mistakess!!! bye-bye good universities</p>

<p>hahahaa man don’t be soo negative, there is always a second time!!! anyway only 2 of the five numbers are common between both lists… the question wasn’t out out both lists what was the probability… it was out of list A which had 5 numbers…</p>

<p>guys, the F(x)G(6)=6 what is x</p>

<p>wasn’t x=6 why is sakata sayin its 3…</p>

<p>wont january be too late for columbia, nyu etc
is there no chance of getting in with a 650 Math?</p>

<p>where did the main thread go??? :(</p>

<p>2011ivy I think it will probably be too late, but you can try it this time and if you don’t get accepted just to the SAT again and send in another application. Better yet, contact these schools and ask if you can take the SAT in Jan. so that your scores will count.</p>

<p>perfectpixie I was looking for it too, but I think the moderators blocked the thread maybe because there were some people posting answers some while before the embargo was lifted.</p>

<p>thanks ill contact them but still what do i do with my horrible scores? :(</p>

<p>2 for the last grid-in
MP and NP are equal</p>

<p>7 weeks needed to save $250 (he already had 75, he gets 25 dollars a week)</p>

<p>zaphira- I agree;I think the thread has been deleted in entirety, but why? The embargo lifted a long time ago, so it shouldn’t matter?</p>

<p>Surely the distance of the midpoints of the two lines is 1?? Right?</p>

<p>How generous do you guys think the curve will be??</p>

<p>The distance between the midpoints is quare root of 2</p>

<p>To anyone with the foresight to have browsed through CC threads in advance, this test could have been an easy 2400. The answers to all the questions on today’s test are right here:

(check the bottom of the page at the second link for threads with CR and W answers).</p>

<p>Does anyone else think it’s a serious issue that this test was exactly the same as the one administered in March in the United States? I understand that College Board reuses some questions and sections – but is it really reasonable to reuse an entire test that was administered under a year ago??? I have friends who drove from Toronto to Buffalo in March to write this test… as far as I know none of them wrote it today in Canada, but if they had then they could easily have aced it just by knowing the questions/passages. Who knows how many people did just that?</p>

<p>P.S. If you read the March '10 threads, you’ll find out that the curves for this test (esp. CR) were brutal. I think it’s something like 3 wrong = 740. And math 2 wrong = 740 I think.</p>

<p>Agrrrr , CB for the international SAT in OCt and November , they alr reused SAT US . And with this curve , im so doomed ><</p>

<p>Anyone remember the question for CS
with the answer “Stigmatized and vindicated”
Thanks loads =)</p>

<p>^^^</p>

<p>No, but, I’m 99% sure that was the right answer.</p>

<p>Does someone still remember the whole question of Tanya? I forgot what I chose and it is really a confusing one for me. thanks.</p>

<p>I remember that only one choice is correct…</p>

<p>The answer was “I only”.</p>
