<p>Many schools were closed today in the NE region. The AMC B date is Feb.
21st. There will be a lot of schools scrambling to switch to B. See the teacher's manual on the AMC site: <a href="http://www.unl.edu/amc/index.shtml%5B/url%5D">http://www.unl.edu/amc/index.shtml</a></p>
<p>damn...it's a lot harder to get 14 correct than 11....at least for me. I didn't make it this year..oh well I made it once and got a 3 on the AIME. That's fine i guess</p>
<p>The alternate date is Wednesday, February 21 (two weeks and a day from now). There is basically zero chance that a third test will be compiled, for two reasons. First, part of the reason for having the second one is to give people who couldn't take the A test for whatever reason a chance to do it. Second, it takes months and months to write these tests--I think they start preparing for next year shortly after this year's round of competitions is over. There's no way they'd try to cobble together another test in under a month (and that's how soon it'd have to be given, to give them time to get it scored by the second AIME date), especially when there's a perfectly good B test in two weeks.</p>
<p>Now if your school isn't going to be open on the B date, that's slightly more complicated. Fortunately, it shouldn't be too hard to find a college or university that's offering it, or even another high school. If you're going to do it at another high school, I suggest you contact the math team coach or AMC coordinator directly, rather than the school administration.</p>
<p>thanks for the advice, everybody...i'll talk to my calc teacher about it tomorrow. hope you all did well!</p>
<p>so you need to answer 14 right to make the 100 mark...and i answered exactly 14 but i guessed randomly on one. haha i hope i guessed right! it was the one about how many numbers are there that one digit is the average of the others...does anyone know what the answer was?</p>

</p>
<p>OMG That is exactly what I did!! Same question too! Are you my long lost twin?</p>
<p>dubisteinschuh-haha wow that is crazzzzy! what did you put...? i think i put c, but im not sure :/</p>
<p>I answered 15. Stupid move on my part; you must get 14 right and 0 wrong, or 15 right and you can get 3 wrong to qualify. I should've guessed on 1-3 more to seal the deal. Now, it's looking like I got at least 1, and probably 2 wrong, with 13 correct. Bahhhhhh.... </p>
<p>And on top of that, I got 99.5 last year. $*!&@($& The AMC hates me.</p>
<p>Did anyone think that this year's AMC was harder than last year's?</p>
<p>How did everyone score and what state are you from?</p>
<p>I think it was easier, and I haven't really studied number theory/geometry/precal since then.</p>
<p>OR
93-99.</p>
<p>I want to say I put B, but I really don't remember. It was a complete, "oh my gosh, the time is up and I have to answer one more question to have a chance at breaking 100" kind of thing.</p>
<p>Discussion of the AMC is NOT allowed yet! Please stop discussing the test until tomorrow (Wednesday). The testing window is still open, and some students may not have taken the test yet.</p>
<p>Yes, the AMC is a test built on integrity. Please please please don't help others gain an unfair advantage by revealing answers early!</p>
<p>It's fine now, though, since the official testing window is closed.</p>
<p>So, then. What did people answer for #15-16? How in the world were you supposed to figure out a+b+c+d+e?</p>
<p>i didnt say anything that would give anyone an advantage...i didnt even say the full question and said i guessed TOTALLY randomly (i.e. im not "giving out answers")</p>
<p>and for the a+b+c+d+e one...was that that one with the (6-a)...ect.?</p>
<p>if so, you just had to pick out numbers that would multiply to get 45 using negatives and positives and then work backwards to find out what the letters were.</p>
<p>Here are the AMC 12 answers. I received these from my math teacher (after the 24 hours had elapsed, of course).
1-C
2-D
3-A
4-A
5-D
6-D
7-C
8-C
9-B
10-A
11-D
12-E
13-B
14-C
15-E
16-C
17-B
18-D
19-E
20-B
21-A
22-D
23-A
24-D
25-E</p>
<p>Oh well. 13 correct, 2 wrong, 10 blank.</p>
<p>And.. WOW. I actually did try taking real factors of 45. Then I for some reason didn't go on. You're right; the way to solve that problem was doing (1<em>-1</em>3<em>-3</em>5), and the key word was they all had to be different numbers, thus the negatives go on the repeat integers, 1 and 3. Cripes, that's elegant.<br>
(6-1)+(6+1)+(6-3)+(6+3)+(6-5)=12+12+1=25.</p>
<p>Does anyone know of any other math competitions besides the AMC/AIME/USAMO?</p>
<p>does anyone know what number the one i was talking about earlier was?? one digit is the average of the other two...</p>
<p>17 right, 8 blank -- 114. </p>
<p>At least I qualified for the AIME under this new standard...</p>
<p>I would have had a 122 on the old scale, dang. =p</p>
