Figuring out the best place to host an international conference in order to prevent jetlag is a tall order for the world's top diplomats, let alone a group of year 9 students.
Yet four Lyneham High School students took on that challenge and succeeded earlier this year, having been named national finalists in the International Mathematical Modelling Challenge.
Enling Liao, Jessica Hill, Emi Callaway and Shannon Lanza were among the youngest students to make it to the national finals in the competition, which required university-level research and critical thinking to develop a mathematical model that would address a problem.
Over five days, the students worked together to decide where a three-day international meeting should be held in order to minimise jetlag and boost the productivity of the participants.
They relied on creative thinking, research and their own knowledge of mathematics to take on the challenge.
"You could also take into account other things such as climate," Emi said.
"There was a lot of pressure. We hadn't done anything like this before, and not as a team," Enling said.
Teacher and team adviser Rajesh Prasad said the students' achievement was incredible.
He said making the finals was all the more impressive given their age compared to their competitors.
"It's all beyond the classroom; getting two years of high school maths and doing this is a huge task," he said.
"They're well ahead of the game. Mathematical modelling isn't a topic at high school, so to do something like this is just wonderful."
The group were one of two at the school to compete in this year's mathematics modelling competition.
They faced off against 80 other teams from across the country.
A year 12 cohort from John Monash Science School in Melbourne and Perth Modern School's year 11 team won the overall national competition, and will be judged against about 50 other solutions from across the world.
The group have plans to study a range of challenging subjects at university, from astrophysics to maths and medicine.
But between now and then, the team said they planned to join in next year's competition.
