Further statistics are shown below. Detailed tables of results by country or contestant are available:
The maximum individual score possible was 42 (which 3 contestants attained). The mean individual score was 14.169, with a standard deviation of 9.875. The following table shows how many contestants attained each possible score.

The following table shows the maximum attainable score, mean score and standard deviation of scores for each individual question.
| Question number | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Maximum score | 7 | 7 | 7 | 7 | 7 | 7 |
| Mean score | 3.449 | 3.557 | 0.591 | 3.896 | 2.267 | 0.409 |

The following table shows the correlation coefficients between the scores on each pair of questions. To make sense of these figures you will probably wish to look at the problems themselves (from Mathlinks) to see which are on similar or different topics.
| 1 | 2 | 3 | 4 | 5 | 6 | |
|---|---|---|---|---|---|---|
| 1 | 0.390 | 0.301 | 0.426 | 0.437 | 0.220 | |
| 2 | 0.390 | 0.326 | 0.366 | 0.515 | 0.230 | |
| 3 | 0.301 | 0.326 | 0.325 | 0.482 | 0.354 | |
| 4 | 0.426 | 0.366 | 0.325 | 0.417 | 0.197 | |
