Class and Battlerank
Each student who passes the Trial of Bonding must participate in the Placement Examination. The Placement Examination is a series of physical and mental tests designed to ascertain in which Class a new student is best placed.
Based on the results of the examination, students are placed in one of the following Classes: S, A, B, C, D, or F.
S is the highest class – reserved for only true geniuses and the stupendously skilled. No incoming student has ever placed in Class S – though it is theoretically possible. Only the top 9 students in Class S are ranked.
A is the second highest class. Gifted, hard working individuals with a degree of inborn talent usually find themselves in Class A. Class A students are highly uncommon but not nearly as rare as Class S. The top 13 students in Class A are Ranked.
B is the class for those with uncommon strength or talent or merely very hard workers. Class B students are dependable in most circumstances and only a little more uncommon than Class C. The top 13 students in Class B are Ranked.
C is the class for the every-man. Class C is where most students of any real value plateau. Most graduate level students have achieved this rank by the time they leave the school. The top 13 students in Class C are Ranked.
D is often referred to as "Developing." Class D students are below average in strength, ability, or pure experience. Many are merely in a developmental stage and will grow more powerful and out of Class D in time. The top 13 students in Class D are ranked.
Class F is most often referred to as "Freshmeat," or "Flunkies." Members of this class are either very new (and possess no particular genius for becoming a Keymaster) or are severely below average in potential and power (in the case of those who can't seem to climb out of Class F). The top 13 students in Class F are ranked. The bottom 13 hold a special, unofficial distinction as well, as being "The Worst."
The top X number of students within a given Class are considered Ranked. Basically, whoever has the highest number of accrued Battlepoints in a given Class hold the Ranks. Rankers (as they're called) hold special privileges (detailed elsewhere).
Each time a student participates in an exam, field test, or other school challenge/event they may gain Battlepoints or BP. Battlepoints may be wagered freely between students in Challenge Matches. Incoming students begin with 0 BP at the bottom of the Class they've been placed in after their Placement Examination.
