The NCEA system has three levels – one, two, and three – corresponding to their respective levels on the National Qualifications Framework. [3] Each level is generally studied in each of the three final years of secondary schooling, [1] with NCEA Level 1 in Year 11, NCEA Level 2 in Year 12, and NCEA Level 3 in Year 13, although it is not uncommon for students to study across multiple levels.
The number of passing grades awarded in each scholarship subject is set at approximately 3% of the size of the Level 3 Cohort. The Level 3 Cohort is the number of students who achieve 14+ credits in the NCEA Level 3 equivalent of said subject. There are two types of passing grade, Scholarship (S) and Outstanding (O).
In 2016, mistakes were made in the 2016 maths exam at every level. [26] In 2017, many students and teachers were left perplexed by NCEA Level 1 MCAT externals, stating that they were "too difficult" and "not in the correct standard". NZQA stated that they had full confidence in their papers, [27] but the minister has asked for a review. [28]
Some subjects were a mixture of internal and external assessments. Internal assessment increased in later years. Subjects such as art, music and design technology were internally assessed by the school and nationally moderated. Originally internal exams were adjusted and scaled to ensure only 50% of students gained a "C" grade or higher.
D grade is a failing grade, corresponding to work receiving less than 50%. However, for Honours degrees, the letter grades also correspond to degree classes, with A+/A/A- grades corresponding to a first, B+/high B corresponding to 2:1, etc. Most universities in New Zealand mark C− as the minimum passing grade.
A Grade 5 was considered a minimum pass at Sixth Form level while a Grade 6 or 7 was the equivalent of a School Certificate level pass in that subject. The pre-allocation of grades available meant that the quality of teaching had no bearing on the overall results of a class.

Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
