I took the Singapore IMO National Team Selection Test yesterday and today. It was like the IMO format i.e. 3 questions to be done in 4.5 hrs each day. The type of questions were: 1. Geometry, 2. Algebra, 3. Combinatorics, 4. Combinatorics, 5. Number Theory, 6. Inequalities. They were taken from the IMO 2009 Shortlist questions (in the IMO, there are Longlist questions and Shortlist questions, and the 6 questions for IMO are selected from the Shortlist questions). I am not supposed to reveal the questions as some other countries may also be using some of these Shortlist questions which were not selected for IMO questions, for their own national selection tests.
Too bad there was only 1 Geometry qn, usually in the IMO there are 2, one for each day. Anyway, I could only solve qn 1, 2, 4, 5 and 6. I think the ever pro Ivan could solve all 6 questions!
*note: this is in fact the 2nd selection test. The 1st selection test with a lower weightage was held about a month ago.
