"It felt pretty good about my results and did a lot better than what I expected. I didn't think I would get such a high percentage [for Australian university entrance]."
He was also offered a $50,000 University of Auckland scholarship but turned it down to study in Australia.
His mother Sandra Rigter said the family was proud of Marc's achievements and that he took on board the words of John Paul College principal Patrick Walsh to work hard and apply himself as it would pay dividends in the future.
"We pretty much just left Marc to it," Mrs Rigter said, adding that leading up to exams a lot of dishes and chores went undone. "There will be lots of visits planned [to Sydney] and it would be good if we can fly in directly from Rotorua."
Marc's CV shows he is not only academically gifted but is a talented sportsman, having represented the Bay of Plenty in cricket and golf. He taught himself how to play the piano, reaching Grade 6 after just six piano lessons, Mrs Rigter said.
Principal Mr Walsh said he formally identified Marc was talented about three years ago and spoke to him of how he had the ability to become school dux. "Marc's results through our testing showed he was very, very bright, but I thought at the time he was cruising. I spoke to him and it just brings home ... that a word of encouragement to a young person can yield huge results," Mr Walsh said.
