A Grade 12 student with the Toronto District Catholic School Board earned perfect scores for all eight of her courses this year.

"A hundred per cent," Brianna Smrke, 18, said Tuesday of her achievement.

According to the Toronto Star, Smrke's feat is even more impressive because she was in the International Baccalaureate program, which is tougher than the regular curriculum.

She did an average of seven hours of homework per day.

But Smrke isn’t resting on her laurels this summer.  The Michael Power/St. Joseph High School graduate has a summer job at the University of Toronto working on a project studying DNA, the building block of life itself.

"I want this to push me to achieve more in university and other phases of my life," she said.

Besides having a demanding summer job, Smrke is also a volunteer.

"Right now, I'm involved in the 'Best Buddies' program at my high school. I'm a friend and a mentor to a special needs student in Grade 9 whose name is Marco."

She has also done volunteer work to fundraise, distribute food to the homeless and acted as a math tutor.

Smrke plans to take some time off in August before beginning arts and science studies at Hamilton's McMaster University.

She hasn't yet determined her career direction, but is considering medicine, more specifically brain research or neurology.

Other smart students

The top student of the Toronto District School Board is Laureen Hachem, who finished with a 99.2 per cent average.

"It's really nice to see all the hard work I've done, like since I was little, pay-off," she said.

Achem spent about five hours per night studying, but said she also left time available for her school clubs.

"You can't work non-stop. That would be too tiring. So it was a balancing act," she said.

Hachem is working as a medical research assistant this summer. She has a full scholarship to the University of Toronto this fall and hopes to eventually study medicine and become a neurosurgeon.

In Peel region, Dimple Dalal matched the accomplishment of Smrke. The Turner Fenton Secondary School student achieved a 100 per cent average in the International Baccalaureate program.

In York region, Evan Feldstein of Westmount Collegiate wasn't far behind. He achieved a 99.83 per cent average.
