Anyone else here taking the AMC? Is it tomorrow for everyone? I'm having a slghtly difficult time waiting...

Good luck if you are!

I am! *is very excited*

I need to do a practice test...
... and get to bed early...
... and finish up that other math contest thing that's due tomorrow...

Good luck to everyone taking part. pipsqueeek briefed me on what it was, I hope you all do well, and get great scores. We do something similar in the UK called the IMC(?). The only abbreviations I remember to do with it are UKMT, UK Mathematics Trust, and IMOK, International Mathematical O-something Kangaroo. I sat the first one last week, actually, and hopefully I'll qualify for the Olympiad again, like last year.

It can be tough, just stay calm and collected, and work through logically.

I have no idea what you are talking about. I assume it is some type of placement test for college. But, regardless, best of luck to all of you!!!!

Oh wow. Thanks for posting this, or I would have COMPLETELY forgotten about it.

Last year I did quite well, and moved on to the AIME.

Anyways, Morningstar, it's a math competition that asks tough multiple-choice questions. If you get 100 on it, you can move on. At 2.5 points for every unanswered question, with 6 for every correct one, you need 11 questions correct to move on. Out of 25, that's not too bad. If you get one wrong, you'll need to get an additional one right to make up for it.

Good luck to all!

I thought it was 1.5 points for every unanswered? Plus none for wrong answers, so you need a bit more than 11

I made it to the AIME last year too

Hopefully again this year.

Oh, and it's probably too late now(?), but it case it's not, or for next year or whatever, I recommend you take the AMC 12, even if you're in 10 grade or below. You only have to get 100 to qualify for the AIME, instead of 120 on the AMC 10, and a good number of the questions are the same anyway.

Hah, I thought we were talking about All My Children...

Really? Our school takes the AMC, but we do it in school for the high math classes.. i don't think that these are the same ones.. I got 16/25 on it, i remember.

So how did everyone do?

I'm fairly sure I made the AIME. I answered 18, and I think I got them all right except for one that was a kinda-guess that might be wrong. But as long as I don't get more than three wrong, I've made it.

*grins*

Yeah, I did about the same. I answered 17, but I'm fairly confident in all of them. And it was 1.5 for every question unanswered, so you need at least 14 correct to move on. Some of those are just so hard...

BTW, it is illegal to talk about the exact questions for a while, so be careful on this thread.

For those who've taken it...

By number, what's your favorite question?

I liked 21. I wasn't able to do it, but someone showed me how later on, and it was a roeally nifty proof.

Zilary · #13 Post by **Zilary** » Wed Feb 07, 2007 1:32 am

Yeah, I definitely did not make it over 100 this year due to the new point system (adds 1.5 for every skipped instead of 2.5). I think I answered 13.

I was an alternate last year with a score of...96? (I think) But I did take the AIME last year, and it was really too hard for me to do anything about it.

Hmm...I liked the clock one. (#8, I believe) Geometry ones have always been my forte.

pipsqueeek · #14 Post by **pipsqueeek** » Wed Feb 07, 2007 1:49 am

yeah, the clock one was cool. Although a ton of people(I think everyone I talked to?) got it wrong because they forgot to divide by two >_<

I liked problem 19(2 triangles, what's the sum of the possible x-coordinates of a). 20 was annoying though. I ended up with something that didn't work. So I guessed

There was one that looked the most right based on what I had, and it shouldn't matter for getting to the aime anyway.

"divide by 2"? Either I used some sort of other method, or I did something wrong. I based my answer on the measures of the resulting triangles.

Agh, I tried 19, but I couldn't figure it out.

Oh, and the cheese problem was nifty. I didn't have the distance formula on my calc (Agh stupid Calcsys), so I just estimated, but I think I was right.

Oh, and the arithmetic sequence one, where you're finding which term is solvable, was cool.
