This year’s International Mathematical Olympiad (IMO) took place in Hong Kong from 6-16 July. The problems can be downloaded from this page or viewed at the Art of Problem Solving (AoPS) forum page for IMO 2016 (here).

* Congratulations to my country, Singapore’s team, for coming in 4th overall!* And for winning the country’s:

**Best**medal haul (4G 2S, previous best was 4G 1S 1B in 2011)**Highest**absolute score (196 out of a possible 252, previous best was 179 in 2011)**2nd best**overall team ranking (4th, best was 3rd in 2011)

Some factoids on the results:

- The Gold, Silver and Bronze medal score cutoffs were
**29, 22 and 16**respectively. Nothing too out of the ordinary. (Interestingly, IMO 2014 had the exact same cutoffs.) - The top 3 countries were the
**United States, South Korea and China**. (These 3 countries were the top 3 in 2015 as well, just a different order: USA, China, South Korea.)- Team USA won a best possible 6 Gold medals. (Next best was 4G 2S by South Korea, China and Singapore.)

- There were
**6**contestants with perfect scores: 3 from South Korea, 2 from USA and 1 from China.- 3 of them were first-time participants of the competition. 2 of them had won Gold in 2015, while the remaining contestant (Allen Liu, USA) had won Gold in 2014 and 2015.

**Question 3**was the most difficult question, with a mean score of 0.251, 91% of students scoring 0 points and only 10 contestants scoring a perfect 7 points. The easiest was**Question 1**with a mean score of 5.272. (The questions from easiest to hardest: 1, 4, 2, 5, 6, 3.)
