Some random comments:

- organisation of IMO failed, a lot of delays, from hotel in Astana we took 6-hr coach ride (!) to the competition venue
- China is the only country that wins 6 Golds; Nie Zipei from China is the only participant with a perfect score of 42

- Belgium beats China in Qn 1 by scoring 42 (i.e. all 6 participants got complete solution for Qn 1) as China scores 'only' 41 in Qn 1, however all 6 Belgium contestants get Honourable Mention (all because of Qn 1, contestants who do not qualify for a medal but score full mark in at least 1 qn will get Honourable Mention)

- Singapore also beats China, Russia, USA and Japan in Qn 1 :)

- Highest team score for Qn 5 is 24. This must be the hardest Qn 5 in the history of IMO.

- North Korea got disqualified. Heard it was because all the contestants use the same lemma (i.e. a proven statement) for Qn 3. You can read more about this incident here in Mathlinks.

- This year's Gold cut-off point of 27 is the lowest in the history of IMO

- Initial cut-off points for Silver and Bronze were 22 and 16 respectively, but Jury voted for 21 and 15. If Bronze cut-off is 16, 43% of contestants are awarded medals (Gold, Silver and Bronze) and if it is 15, 51% are awarded medals.
