It all adds up for Pickering teen: Hannah Dossa lands perfect score in math contestMay 30 2015 By Jillian Follert PICKERING — Hannah Dossa, a student at William Dunbar Public School, got a perfect score in the Gauss Contest, organized by the Centre for Education in Mathematics and Computing at the University of Waterloo. Only about one percent of students get a perfect score on this math test.

Earlier this month, Hannah Dossa, 13, got a perfect 150 in the Gauss contest, organized by the Centre for Education in Mathematics and Computing at the University of Waterloo.

In 2014, only about one per cent of the 78,963 students who participated in the contest achieved a perfect score.

Even high scores were hard to come by — 14 per cent of Grade 7 students got between 136 and 150.

“I was very surprised,” says Hannah, a Grade 7 student at William Dunbar P.S. in Pickering. “I wasn’t sure about the last question and I didn’t think I did that well.”
The test — which is open to Grade 7 and 8 students across Canada as well as internationally — features 25 multiple choice questions on a range of math topics learned in class including algebra, geometry, patterning, data management and measurement.

It starts with the easiest questions and gets progressively more difficult.

The results don’t have any impact on a student’s math grade — taking the test is meant to be a personal challenge.

Hannah says she has always liked math and that her mom started teaching it to her at home from an early age.

“I find it very interesting and very challenging,” she says, noting that her favourite topic is algebra.
