Isn't this olympiad's age requirement is smaller or equal to 2011. As I know JahonaliX is 2010 student.
Not exactly 2011, age must be <= 15.
When invitation from KHIMIO came to us(I am team leader). It said you have to be born after 26/12/2010.

7. The International Olympiad is held for students under the age of 16 at the day of the contest; studying in general education schools. Team members register online to participate in the International Olympiad.

I think Jahonali can not participate, because he is born before 25 decemeber
as said in the rules anyone below 16 can participate in this olympiad
JahonaliX is still 15
understood
