<p>I was just wondering because I remember something about international students need to be recommended by the teachers, school, etc.</p>
<p>In Canada anyway, we write exams; top scorers then meet somewhere (this year for Chem it was in Toronto) to undergo further selection (I think they go to lectures, perform experiments, and write more exams)</p>
<p>What about other countries? Like China, India, Japan etc?</p>
<p>in australia, we have an exam, called the National Qualifying Exam. If you’re in the top 20 in the country in that test for a subject (ie physics olympiad, biology olympiad etc.), then you get invited to a special training course where you get accelerated study on the subjects. At the end, you have several exams, including written and practical exam, from which 4 students are chosen to go to the International Olympiad</p>
<p>What hapens if you’re boarding in America yet you’re Australian? </p>
<p>Guess I’m unlucky (not really as I can never presume I’ll get the marks)</p>
<p>I believe in China, they have county-level, state-level and finally national-level olympiads in the specific subjects, where the top X% are selected to go for a “winter camp” of accelerated study, after which they write more exams and the national team is formed.</p>
<p>If you are in America but you are Australian, you can qualify for the US-team training camps in the national olympiads (USNCO, USACO, etc…), but you can’t actually attend them I think.</p>
<p>You give the regional level, then the national level and then if you qualify (obviously!) you are invited to the int’l. So in India the process for maths is — RMO -> INMO -> IMO. I believe its the same elsewhere too!</p>
<p>In my country they have a test for each subject. The top 50 or somefin get invited for training camps. After 2 more shortlistings 5-6 ppl get to represent the nation in the IMO/IPO/ICO/IBO</p>
<p>it depends on the country. what’s OP’s country?</p>
<p>in short, you can participate in the NATIONAL olympiad of your school’s country, but can represent only the country of your citizenship in the INTERNATIONAL olympiad. correct me if i’m wrong.</p>
<p>i.e. if you’re not studying in your country of citizenship, you can forget about international olympiads.</p>
<p>international olympiads are pretty much impossible anyway.</p>
<p>i think for every country it’s just serious of exams tho</p>
<p>a series of exams*</p>
<p>why couldn’t i edit the first one???</p>
<p>You can only edit within a certain time period.</p>
<p>In general, it is a series of exams. Lolz. I can say that for Taipei and Singapore and Australia and China and India and Belgium. Malaysia system a bit weird though, they administer the first test barely 1-2 months after the previous year’s IChO. </p>
<p>Olympiad is an awesome experience 
Though it is insane to get in, I do agree.</p>
<p>Me country is China, not my nationality. And I don’t go to local schools. So basically, am I screwed?</p>
<p>I think I’m screwed as I go to a boarding school in America yet have Australian citizenship etc. Do I get to compete in American National exams though?</p>
<p>aisgzdavinci - So you’re studying in China but citizen of another country? I don’t think you have much opportunity, especially if you don’t read Chinese.</p>
<p>Shore - Yes you can compete in USAMO, USACO, etc. But you can’t go to the camps.</p>
<p>shore, im not 100% sure, but i think you have to be a U.S. citizen to be on the U.S. Olympiad team. For the Australian team, you must be an Australian citizen. So if you wanted to get to Olympiad as an Australian, you would have to take the Australian National Qualifying Exam.</p>
<p>For the US, this depends on the Olympiad. The Chemistry Olympiad requires that you be a citizen of the US. I’m pretty sure for Math, you can be a permanent resident. For the US IOI team, there they’re really lenient, since there was a girl from China who was studying as an exchange student in the US for a year who made the team.</p>
<p>At least in my knowledge none of the Intl Olimp have the rule that restrict participants must have nationality of the participating country.
So I think as long as you do well at the TSTs they will let you</p>
