Springwood High Year 12 students had to endure more pressure than normal as they sat their Higher School Certificate (HSC) exams while flames devoured bushland perilously close to their school.
Rural Fire Service Commissioner Shane Fitzsimmons says all the students got through the modern history exam safely.
"We had some high school students sitting exams in that school, I understand, but they've all been accounted for," he said.
"They're all good, they are in the school.
"We've met up with school authorities, the principal, the teachers and the students are okay. They are all accounted for and they're okay."
