*Official* AMC 12 2012 Prep Forum

<p>Hey guys, I'm a junior, taking the AMC 12 this year. I really am hoping qualify for AIME this year, I've score mid 90's but never over 100 yet. I just wanted to start a forum for anyone who's going to take it with hopes of qualifying for AIME, and anyone whose done so before and can give us some advice.</p>

<p>Thanks</p>

<p>I'm with you in the AMC, but there are so few of us here that are that interested/good at math that it's not worth it.</p>

<p>Hey I made USNCO and USAMO... best way to prepare for AMC is just doing past practice tests.</p>

<p>Started out with only a 110ish freshman year but eventually was able to get up to 135/141.</p>

<p>wow, and thanks cortana</p>

<p>Agree with the practice tests; also buy the AoPS books and start working through. also, CC is probably not the best place to come for math competition stuff.</p>

<p>I'm starting to work for this year too. This will be my first time taking the 12 (I've taken the 10 before), and I'm hoping to qualify for the AIME this year as well.</p>

<p>I think I'll try for UNSCO this year as well. I just took half of last year's test and I haven't missed a question yet (and I haven't even thought about Chemistry since June).</p>

<p>I have lots of practice ahead of me.</p>

<p>Is it possible to get extended time on AMC, if you get it on the SAT?</p>

<p>Honestly, I think I would have a shot at a 150 with extended time.</p>

<p>^I agree. Some questions in the #21-#25 range take significantly long to figure out.....</p>

<p>Unless of course there is 1 formula to trivialize the whole problem like last year haha.</p>

<p>A bit late finding this thread, but some important, important information. </p>

<p>The Art of Problem Solving Vol. 2 is your best friend. Assuming you can understand it, it makes you think at such a critical level that AMC 12 problems will seem significantly less demanding, though they still aren't easy (shows you how complex the book is). However, most crucial is the way of approaching problems. Not only does the book help a lot with concepts for me people not so experienced in math like me, but it makes you think like a mathematician which is crucial to doing well on AMC 12/AIME/USAMO.</p>

<p>what is a good way to practice without buying the books? just doing the practice tests on artofproblemsolving.com?</p>

<p>wow i feel like an idiot. i opened up an 2011 amc 12-b on AoPS and could only get 10 questions solved before getting stuck lol. do you guys think i could improve to 100+ before testing date?(i think i have a fairly decent aptitude for learning- 2250 SAT without much prep,strong grades in AP chem+calc, but then again everyone taking these tests is very gifted I'm sure). Also how do I register for this? I'm a senior and have never done this before. Do i register online or through my school?</p>

<p>ALSO, can someone clarify the solution to this problem please?

<p>is it asking for the area not in A,B,and C, or the area that is exclusive just to c with no a or b included? I'm also a little confused on why they did what they did. if you subtract the area of triangle mdb from 1/4th of the area of circle b, doesn't that still leave some area that is both in circle b and c?</p>

<p>ok nevermind sorry lol. i apologize for posting so often in this tread(triple post -_-). I finally understand that problem above but i'm a little confused with this one
AoPS</a> Forum - Ratio of area of EFGH to area of ABCD • Art of Problem Solving</p>

<p>are they assuming that all the sides of abcd are broken up into 7/8 and 1/8 segments by the vertexes of the smaller square? and then using pythagorean's to find the length of one of the sides?

<p>Does anyone know how many points you usually need to make it to AIME?</p>

<p>For the AMC 10, the cutoff is almost always 120, but occasionally, it's 118.5.</p>

<p>For the AMC 12, from 2007-2008, the cutoff was 97, but in 2010 it was 88.5 and in 2011 it was 93.0, so it's really unpredictable. But if you score at least 100, then you automatically qualify for the AIME.</p>

<p>PM for answers. verification needed</p>

<p>can someone PM me answers? with numbers would be appreciated cuz i didn't write the letters down.... wasn't allowed.</p>

<p>Same, can someone please PM me answers, with numbers preferable? Thanks!!</p>

<p>Can someone send me the answers?!! With numbers? Thanks!</p>

<p>can somebody discuss the answers with me? I'll give proof.</p>

<p>Can someone lay out a general guide for this? I'm taking the 12B on the 22nd. I mostly just need common formulas and techniques that show up on the test, I don't know many but if I knew some of the most common ones I'd say I have a pretty good chance at qualifying.</p>
