"I've never been good with numbers and I find it boring. I'm more of a creative person and it's hard to be good at both."
Studying special effects make-up, Chontelle is not one to ever be seen without a full face of make-up. Even on the sports field or out in the desert.
"I'm into sports and I've been to central Australia camping. So I'm a bit of a tomboy and a Beauty. But I still have my make-up on when I'm camping," she says.
Admitting she's a carbon copy of her mum, she says: "She wears make-up and she's very girly. She's like me and loves shopping. Like mother like daughter."
While Chontelle is extroverted and confident now, she says she didn't always command attention when she walked into a room.
"When I was younger I didn't get a lot of attention like I do now. When I go out and I've got my heels and make-up on people do look. As I got older I got more confidence."
But Chontelle proclaims her inner Beauty to be her best asset.
"I have inner Beauty more than anything. Because I'm friendly and down to earth and I think you need inner Beauty more than anything, more than looks."
But she does admit she might focus too much on her outward appearance and is hoping the Geeks may help her to change this.
"Well I'm hoping I might learn not to worry so much about my looks maybe. Because I do worry about that a fair bit; about always having my hair and make-up done. So maybe a bit more on the brains side of things because I didn't really concentrate that much at school because I didn't really find it that important. Maybe they can teach me a bit about that."
In return Chontelle wants to share her confidence with the Geeks.
"I want to help them just to come out of their shells and not be shy and just be who you are and not be afraid. Being happy being yourself I guess more than anything."
And she's hoping to win something along the way to replace her only other award to date – being crowned the Most Likely to be the Next Paris Hilton at high school.
