Australian Mathematics Olympiad



The Australian Intermediate Mathematics Olympiad (AIMO) is the pinnacle of the enrichment program provided in mathematics at PLC Sydney. It is an annual competition open to students up to Year 10 across Australian schools. The four hour Competition stretches students to the limit. This year 1829 students from 187 schools participated. This shows the select nature of entry. You have to know far more than the regular mathematics curriculum. You have to be able to apply your knowledge across a range of different mathematical contexts, showing imagination and creativity. The 10 questions increase in difficulty until the final two which are allocated additional marks.

This year we invited 17 students from Years 910 to participate. PLC Sydney enters more students than other schools in this competition. Thus our percentages below reflect this commitment to provide this opportunity to many girls. In preparation, the Year 9 accelerated class were given regular support throughout the year from Mr Sinclair and Dr Dawe. The Year 10 accelerated class were seen infrequently by Dr Dawe due to the heavy program of the senior curriculum. The enrichment activities for them are optional.

The table shows the performance of PLC Sydney students in comparison with their peers across Australia. They have done exceptionally well. Five of our Year 9 students achieved the top six places, amongst our PLC Sydney participants, showing that their preparation through the enrichment program had a marked effect.

First place, with a high distinction, went to Tay Leung (Year 9) closely followed by Rebekah Kang (Year 10) with a distinction. What is really encouraging is that 12 of the 17 who entered received a credit or above.

It was great to see a number of our students attempting the difficult problems. Chistina Shi (Year 9) obtained full marks for question 9 and Salina Ai (Year 10) was the only participant to score marks for question 10.

The girls deserve our warmest congratulations.
