Classes within Guardian institutions are not assigned according to the level of experience or skill, rather they are set up based on a combination of the following:
+Natural talent
+Social hierarchy
+Financial standing
+Political influence and power
Because of these defining criteria, a student will be placed accordingly from class A through E and F is reserved for students whose only merit is skills, abilities and talent but are within the lowest of social standings.
With this system, classes higher in the pecking order are allowed to scout students from lower degree classes. Another statute that accompanies the established regulations is that a student unless scouted will remain in their class until graduation.
It is also possible to resign to another class so long as compensation is given to the class he is leaving. Lower degree classes are also permitted to poach students in higher degree classes but they have to pay a tribute or meet some other demands.
If a class happens to fall below the recommended amount of students, the whole will be expelled.
