"Oh, yeah. Explain what you mean by 'struggling'?" mocked Silas.
Reve simply pouted in response.
The premature magical education system of NIRA took most of its ideas from its parent organization in the new continent. It implemented the advanced grading concept, as well as merged it with the ancient Arcadian magic prowess grading.
A student would be graded based on their tests and understanding of the class. After all was said and done, the teacher would assess the student and give a grade that ranged from the ancient arcadian characters; Fz, Az, and Sz. Those characters had a deep intonation as they represented the first letters of three runic words; Fayz, Assez, Sarz. It was unknown what the words meant, and by the time people started to wonder, the grading custom had already stuck permanently.
'Fz' usually means bad. It denoted the failing of the student.
'Az' indicated that the student did well.
