Hi Everyone,

I'm delighted to announce that registration is now open for the **Fall 2013 Online Math Open**! Thank you all for your patience.

For those of you that don't already know, the Online Math Open (OMO) is a team-based contest, where teams of up to four students are given over a week to solve 30 short-answer problems. The contest is completely free, and takes place over the Internet -- therefore, students may team up with anyone they like around the world.

This year's contest will take place from **October 18 through October 29, 2013**.

Starting this year, the contest itself will be hosted on internetolympiad.org. Team captains can register a team of up to four students there by clicking the link labeled "Register/Update Team". Note that, in particular, **only the team captain needs to register on the website**. For more information, please check the information page on our website.

We work extremely hard to ensure our questions are of the highest quality, so that even the easy problems will be interesting, non-routine, and not "just another contest problem". (You can see some of our previous problems, including discussion, in the contest section of AoPS .) We hope you enjoy this year's problems as well!

Best, The OMO Team

Hello,Michael can I know,at what age students in USA graduated?

Log in to reply

Students generally graduate when they are 18 or 17, although there are some who graduate early or late.

Hello all,

If anybody would like me to facilitate e-introductions between any of you, so you can coordinate OMO participation with people you only know via Brilliant, then let me know.

Instead of posting email addresses publicly here, just contact me at discussions@brilliant.org if you would like to contact someone. I will check with both parties, and then email you the contacts of people who want to be on a team with you.

Have fun!

Two questions that arise for me: 1) Is there an age-restriction on the participants? 2) How does the Team enforce the prohibition of graphing tools and such?

Log in to reply

There is an age-restriction. It says he mustn't graduate from high school

Log in to reply

Thank you! I missed that :)

Log in to reply

There is no way I think they can enforce the prohibition of graphic tools and such. I have graduated from school and won't be eligible for the competition. But I am participating just for fun. Would you like to team up with me, Sir?

Log in to reply

I can't predict how much time I will have, but I would like to participate for fun as well :) Let's team up :)

Log in to reply

Did you register a team yet?

I've had contact with the organisation and it should be no problem to participate off the record. Just add '(off-record)'in the team name.

I can ask a friend of mine to join in as well :)

Log in to reply

For now, I have registered with name 'ICE(off record)'; it can be changed anytime.

Sure, ask your friend to join as well. It would be nice.

Log in to reply

Should you need to contact me, my email is listed on my profile page :)

Log in to reply

How to submit the answers..? How will be the interface..???

Log in to reply

read the website.

Log in to reply

Four members are not a requirement; I believe there have been teams in the past with only one person. Obviously, however, he is at a clear disadvantage.

Log in to reply

Hi AkshajK! and anyone want to team with me?

Log in to reply

Hey there AK! Just wanted to know, are you a problem writer?

Log in to reply

No he is not.

Log in to reply

I'm reading questions from past competitions and I have to say, they are quite impressive. Really. I certainly will be signing up; thanks for introducing me to this Akshaj.

Log in to reply

Can you give the link from where you're reading the past questions? It would be easier to not have to go through the whole website searching for the past questions.

Log in to reply

there's a whole tab to past problems.

Log in to reply

darn AK you don't run this contest :P

anyways, I have a team with (Kevin C. (lucylai) and some other people. Hi ahan, willcui, and chao

Log in to reply

Wait, why are you saying hello to me? And check the spelling of my name.

Log in to reply

"up to four students"

Pretty self-explanatory? Basically, no, you don't need four students. I once participated alone.

Log in to reply

I have a question. What if the high school system is different from country to country for example, here in the philippines, I graduated high school last SY2012-2013, but the high school system is from 1st-4th year only.

Log in to reply

Log in to reply

I didn't know this existed until I read this, I am creating a team with some of my classmates, thankyou for introducing this to me

Log in to reply

can we participate indivisually? what is the age restriction?

Log in to reply

Yes, you can participate individually (or have a team of 1 person) if you want to. Students must not have graduated from college.

Log in to reply

Who wants to team up with me?

Log in to reply

Interesting but i have my examinations to take care of.-SMOJ

Log in to reply

Do the team members, which we choose, also need to have their accounts on NIMO...?????

Log in to reply

Only the team leader needs to have an account.

Log in to reply

Let me see if I understood correctly: During the competition i can enter as many times as i want to the web page and see the problems? I mean, if I open problem number one, that doesn't means that i'm forced to answer it at that specific moment, right?

Log in to reply

You receive all problems at the beginning of the competition. You can submit any answers as many times as you want during the week, and your most recent submissions for each problem are graded at the end of the competition. No feedback about whether your answer is right will be provided until the submission period is over.

Log in to reply

sorry, but could you please specify the requirements for registering contest?

Log in to reply

Registration information and rules are here: http://internetolympiad.org/pages/14-omo_info Teams of up to 4 students should register under the account of one team captain.
