"I better go out, the phone will be ringing all day again I expect."
Dawson, now 89, has fond memories of the three years she spent studying high school maths by correspondence, culminating in the B1 grade School Certificate pass.
She also studied French and embroidery.
"I just did it for fun; I always liked figures. My family thought I was crazy but I just wanted to see if I could do it."
And do it she could.
No wonder, Dawson was a bit of an ace in the classroom as a youngster in her native Scotland. Plus, after raising two children she knew how to knuckle down and get on with it.
As a child her results always topped 80 per cent, and her good grades continued before the School Certificate exam.
Unfortunately, nerves got the better of her in the exam and although happy to pass, she had expected higher marks, Dawson said.
"I wasn't even going to sit the exam, I was so petrified. But everyone said I should, so I did."
The nerves continued as she waited for the postie to arrive the day the results were due, she said.
"I was waiting and waiting for the post that day, I was very nervous."
It was to be the end of her formal studies, and no she didn't - formally, at least - do anything with the skills she learned.
But they were still useful in everyday life. Even now, she says her French vocabulary gives her an edge in the daily crossword.
"I didn't use it to do anything, just to keep my mind active."
Her thoughts are with the 143,000 Kiwi school students embarking on end-of-year NCEA exams, which began on Friday.
"My advice to them would just be to keep cool. But, then again, young people have got so much more confidence nowadays so I'm sure they will be fine."
