Principal John Clarke said about 30 per cent of year twelve students are choosing to pursue university studies since they adopted the program six years ago.

"It's been extremely successful, we've gone from 5 pc to 30 pc of students now wanting to go on to uni," he said.

The College 3+3 model allows students to complete their HSC over two years.

"Students concentrate on three subjects at a time and they become experts in those three subjects and with that achieve better results in the HSC," Mr Clarke said.

One outstanding student from the year 2012 class was Charlotte Lembit whose high scores allowed her entry into her first preference choice to study a Bachelor of Art History and Curatorship at the ANU.

"I've always been interested in art, ever since I was little I thought it was an interesting subject and hopefully one day I'll be able to work in an art gallery," she said.

Miss Lembit achieved a band six in Ancient History, three band fives in Modern History, Mathematics and Art, two band fours in Chemistry and Advanced English and 25/50 for History Extension.

She said she was surprised but satisfied with her ATAR of 84.95."Some [results] weren't as good as I hoped, I thought I would do better in advanced english but I'm happy overall," she said. 

"I'm pretty happy with my ATAR as I didn't think it would be as high with the marks I got."

Miss Lembit said spreading the HSC over two years allowed her to concentrate on specific subjects. She was also lucky in that her final exams were more spread out.Her advice to other year 11 and 12 students completing the HSC was to stay consistent.

"Even thought it's split into two years, you still need to stay focused and keep on top of your work. If you miss classes it's hard to catch up," she said. 

"A lot of people didn't try as hard in the first year but you have to remember to stay consistent."The 18-year-old hasn't been deterred from studying after two years of hard slog. In fact, she said she is looking forward to university life and can't wait to get stuck back into the books.

"I'm excited, I'm looking forward to being back in school. I miss it. I like making notes and doing work," she said. 

"[With university] I can concentrate on the things I like to study rather than studying for the sake of getting good marks and things like that."
