Otumoetai College principal Russell Gordon said the team had been busy fundraising for their flights to the US.
"They were really putting all of their energy into getting the funds and were quite drained," he said. "But once you get into competition mode that falls away."
Gordon said all had been quiet since the team left for the world championships which would be held between April 25-28.
However, he guessed the team would now be in "competition mode".
The principal said regardless of the result, he was pleased the students had the opportunity to showcase their skills worldwide.
"For them to win, lose, or draw they are there to have that life experience," he said.
Gordon said the team would miss the beginning of term three by the time they returned from the competition.
"They will be fully immersed in what they are doing there and they will come back and [be] going straight into the academic side of things. But they are the kind of kids who will be able to cope with that," he said.
"I am sure when they come back it will be a big blur, so we just hope they have time at least to reflect on what they have achieved."
