The 34-year-old said it was not easy studying, working various jobs, travelling for the student association and meeting the needs of her family.
"It was absolute craziness, I was working seven days and there were many late nights. My husband and kids got quite used to people coming out to our house who needed help with questions, having a meal and studying," she said. "I had to give a lot of apologies to my friends for not being able to attend things and they were really good. A couple of times I would come home and they had cleaned the house for me.
"My mother-in-law has been amazing and the support of my husband Stefan and family helped us get through it."
Mrs Smith is continuing to study a post-graduate diploma in infection control.
"What I really want to do is go into education for infection control issues. I have a passion for elderly and for elderly people to stay in their homes longer. So I would like to maintain ways for them to be able to keep as much of their dignity by being at home."
She said also being recognised for the help she gave other students was "totally unexpected".
"It blew my socks off because it's something I'm quite passionate about, so it's really lovely to be able to receive this award and for my children to see their mummy get up on stage and realise that this was what all the hard work and visits from other students wanting help and advice was for," she said.
