<p>oh really, there is an 88.5 cutoff before??? =[] that gives me some hope… I already know what I got wrong… I got the last 4 Questions and first 5 questions for sure… but I totally mess up the questions in the middle (I know, I feel dumb haha)</p>

<p>Cortana the wording of that question was crazy, i was confused haha how did you approach it ( q 15)</p>

<p>now i begin to hate those AoPS ppl… they all score like 140+… hope everyone else bombed the test too…lets have a new low record cutoff score!!!</p>

<p>newchie123 for hexagon just draw it out and ull see that hexagon+one extra circle = answer</p>

<p>The reason why people score so high is the ability to think fast. Me for example If i got an extra hour I couldve easily obtained 130. But they make it pressured, you need to go fast but come up with an efficient solution. Thats the difference between me and some crazy people, not necessarily about our knowledge of math, but the process we go through.</p>

<p>q 15 i meant lol not the hexagon that was easy.</p>

<p>I should’ve guessed on the last 4 questions… They were all the same answers :/</p>

<p>does someone have answers that could pm them to me?
@cortana how do you know that?</p>

<p>did anyone get q18, its was something like a triangle with sides of 24 25 26, find BI?</p>

<p>I don’t think they were, I only got 3 of them as the same answer… O_O</p>

<p>I agree with Steven if I had more time I could’ve got more right.</p>

<p>15 didn’t turn out too bad; there are 2^9=512 possibilities and when you look at the possible cases there is a pattern which adds up to 49 so 49/512</p>

<p>Yeah i noticed throughout the contest alot of answer choices were similar so i was tempted to guess, but that meant me going to aime or not so I decided not to risk it and leave it blank :/</p>

<p>Yes all of the last 4 were the same. </p>

<p>for number 18 consider using herons formula then the angle bisector thereom. Its not the cleanest but hey it works.</p>

<p>answer for 18? i used the way you did, but not sure if its right?</p>

<p>My testing coordinator showed us the solution pamphlet after the test</p>

<p>cortana what was the highest score at your school a kid got 121 here, hes a beast and he made some silly mistakes he couldve potentially gotten near 150.</p>

<p>it’s only six in hawaii >.> i sound like such a party pooper.</p>

<p>okok…
answer for q18 PM?</p>

<p>The highest in my school was a 91 lol. He actually got the same number right as me but I answered a lot more questions</p>

<p>cmon no one PM me the answer for q 18? newchie?</p>

<p>Can someone PM me the answers? I can prove that I did indeed take it, if necessary. Thanks!</p>
