We get a full scholarship for university education (up to post-doc iirc), but you need to "pay back" by working in the government sector for the same number of years that you used the scholarship.

There's also a company that gives money and rice, but I'm not sure how much since they'll give it later.

These prices are prices for any international science olympiad (e.g. IMO participants' rewards are also this much.)

There is also a program in which if you get an international medal you can get an automatic 100% score from YKS (Exams for Institutions of Higher Education), and enter any Turkish university (e.g. METU).

The money is given by TÜBİTAK, the governmental organization in charge of all the science-related stuff, and science olympiads.

3 million dollar in the US for gold medal.

Italy:

• Gold: 1200€

• Silver: 1000€

In Uzbekistan generally for any International olympiad be it an IOI,IMO,IBO,ICHO our country pays around 80.000$ for gold, 48.000$ for silver and 33.000$ for bronze.(Not exactly but the difference is not that high)
