On Friday and Saturday, the NZIMO team took the two exams consisting the IMO. You can find the problems here (select a language next to 2015 and click 'Download'), or here in English. Do you think you can do them?
The IMO teams are now on a holiday, going on various excursions and enjoying their time in Thailand while the leaders and deputy leaders slave away at interpreting unidentified symbols on their students' scripts and argue for marks for the "perfect solution with a serious flaw" (Arkardii Slinko, 2004).
Here are some photos from the official IMO 2015 Facebook page:
We'll have more photos once the NZ team move their photos to their computers!
