2011 Camp Selection Problems – due 10th August 2011

Chris — Mon, 27 Jun 2011 23:11:28 +0000

Our first step in choosing the team to represent New Zealand at the 2012 IMO in Argentina is to choose 24 students to attend a week long training camp in Auckland in January. These students will be chosen using the 2011 Camp Selection Problems (pdf, 111k). Students submitting solutions to the Camp Selection Problems must intend to be in school in 2012; must have been born on or after 20 July 1992; and must be NZ citizens or hold NZ Resident status.

Those selected for the camp will do 1-2 assignments prior to the camp, and we hope to have them sit Round 1 of the British Mathematical Olympiad in December. At the camp in January we will choose a squad of 10-12 students for further training, and to take part in several international competitions, including the Australian and Asia-Pacific Mathematical Olympiads. The final team of six will be chosen based on the results of these competitions, and perhaps some additional selection tests, if needed.

We look forward to receiving your solutions!

PS: The 2011 team will be departing soon for the 2011 IMO, in Amsterdam. Watch this space for news!

Here is the first lot of monthly problems – the April Problems.

These problems are intended to help students prepare for the 2011 camp selection problems, used to choose students to attend our week-long residential training camp in January.

The solutions will be posted in about one month’s time, but can be obtained before then by email if you write to one of us with evidence that you’ve tried the problems seriously.

Good luck!

2010 Camp Selection Problems – due 27th August 2010

Chris — Sun, 01 Aug 2010 09:15:11 +0000

With one IMO concluded – and so successfully for New Zealand! – it’s time to start thinking about the next.

Our first step in choosing the team to represent New Zealand at the 2011 IMO in Amsterdam is to choose 24 students to attend a week long training camp in Christchurch in January. These students will be chosen using the 2010 Camp Selection Problems (pdf, 105kb). Students submitting solutions to the Camp Selection Problems must intend to be in school in 2011; must have been born on or after 20 July 1991; and must be NZ citizens or hold NZ Resident status.

Those selected for the camp will do 1-2 assignments as preparation for sitting Round 1 of the British Mathematical Olympiad in December. At the camp in January we will choose a squad of 10-12 students for further training, and to sit the Australian and Asia-Pacific Mathematical Olympiads and Round 2 of the BMO. The final team of six will be chosen based on the results of these competions, and perhaps some additional selection tests, if needed.

We look forward to receiving your solutions!

Important update, 11th August: At last January’s camp we decided that only year 12 students and members of the squad would be required to do just the senior problems; students in year 11 or below, who have been to a January camp but not been in the squad, can do both the junior and senior problems. The instructions for the problems have been updated to reflect this.

Files (all pdf):

the problems only
the instructions and registration form only
Both in one.
