"It's important not to compare your efforts to what other people are doing because that's when you start to put pressure on yourself and you lose confidence," Rebecca said.
"If you know you have done as much study as you could and you go into the exam and give it your best go then you should be proud of yourself."
Rebecca said she wanted to finish her schooling with good grades before she moved to Auckland next year to start university.
John Paul College principal Patrick Walsh said teachers had been holding extra tutorials for students at lunch time, after school and on weekends.
"Exams are starting a bit earlier which does put pressure on students and teachers to get through the syllabus in time and that can be quite stressful for them.
"But in saying that, students are not as heavily reliant on exams as they can get the majority of their credits through internal assessments."
He said the school had sent messages to parents encouraging them to make sure students had study timetables, were sleeping and eating well and had cut down part-time work in the lead-up to exams.
Rotorua Lakes High School deputy principal Jo Sturme said examinations were at the forefront of everybody's minds.
"There are always those few students who have a more stressful lead-up to exams just as there are always those who thrive during exam time. There has been the odd tear here and there but for the most part it has been fine."
She said the school had a revision "guru" visit classes to give students study tips and "make sure they are looking after themselves".
