Cowan has already secured a $10,000 scholarship, guaranteed paid work experience after her second year of study from WRMK Lawyers Scholarship.
Now that her results were back, she could send through her acceptance into Victoria University, Wellington, and receive the scholarship properly, she said.
"I think the delay [in NCEA exams] helped me because I was able to bump up the three exams I did sit from what they were to excellence."
Whangarei Girls' High School principal Anne Cooper said the unexpected grade events helped a lot of students in a very difficult year.
Although she did not personally receive a lot of feedback, from what she heard it was the usual mixture.
"Some very happy with their results and others who are a bit disappointed."
Exam attendance among students in Northland was significantly affected by Covid-19, with students absent for 43% of externally assessed standards, compared with 18.1% absence across this region in 2020.
Nationally, 27.3% of students were absent for an externally assessed standard in 2021, compared with 11.5% in 2020.
NZQA deputy chief executive, assessment, Andrea Gray said while NZQA always expected students to attend exams where possible, they anticipated Covid-19 would have a considerable impact on attendance.
"In the areas most affected by lockdown – Auckland, Northland, and parts of Waikato – the Unexpected Event Grade process gave students reassurance they could still receive a grade even if they were unable to attend the exam.
"Every year, teachers gather evidence of students' learning and send grades to NZQA. These grades have undergone a quality assurance process to make sure they are fair and relate to the standard being assessed."
