Over All Abilities (OAA) app is an app distributed by the current Student Council President, Miyabi Nagumo, that displays each student's abilities assessment. It is based on school results in which it is speculated that any student, whose overall ability score gets lower than the certain baseline will, receive a penalty.
OAA : over all ability
Have seven layer
OAA – Social Skills / Communication skills
OAA – physical ability
OAA – academics ability
OAA – sport ability
OAA – Social Contribution
OAA – Adaptability
And overall abilitys.

It is an application distributed by Miyabi Nagumo (the current Student Council President).
Purpose: It displays a numerical and qualitative assessment of each student's abilities across multiple categories.
It works as a transparent ranking tool—teachers, students, and possibly the school administration can see a breakdown of strengths and weaknesses.
Speculation: If a student's Overall Ability Score drops below a certain baseline, penalties or demotion may occur (such as possible expulsion risk, loss of privileges, or restrictions).

📊 The Seven Layers of OAA
OAA measures students in seven distinct categories:
1. Social Skills / Communication Skills
Measures interpersonal ability, charisma, persuasion, cooperation, good at talking and leadership.
Important in exams involving teamwork or negotiations.
2. Physical Ability
Measures raw strength, stamina, speed, reflexes, and overall athleticism.
Tested in sports, physical trials, and survival exams.
3. Academic Ability
Measures intelligence, memorization, reasoning, and exam performance.
Strongly tied to written tests and knowledge-based assessments.
4. OAA – Sports Ability
(This is often confused with Physical and Ability, but Nagumo separated them.)
Physical ability = natural body strength & fitness.
Sports ability = practical use of physical skills in real games.
Measures:
Team coordination in sports.
Tactical understanding of rules.
Performance in official sports festival events.
5. OAA – Social Contribution
Calculated based on a variety of factors, such as your general attitude during class, your attendance record, the presence of any potentially problematic behavior, or your contribution to the school through programs like the student council.
6. OAA – Adaptability
Calculated based on your capacity to adapt to the world around you.This includes, but is not limited to whether or not you consistently demonstrate the ability to think on your feet, your communication skills, the size of your social circle, and whether or not you act in a way befitting of your social standing amongst said circle.
Overall Ability: A student's comprehensive ability is derived from each of the four values calculated above. However, the effect Social Contribution has on the overall score is reduced by half compared to the other three values.
A composite score.
Calculated by combining all six categories.
Weight distribution is not fully transparent, but academics, adaptability, and social skills usually carry slightly more weight.
Used to:
Rank students across the whole school.
Decide if a student is at risk of penalties (expulsion, warnings, demotion).
Compare across classes (fueling Nagumo's competitive vision).

Ranking System (Qualitative Conversion)
Each category and the overall ability are graded from E up to S.
E Rank → Below Average,
D Rank → above average.
C rank → far above average
C Rank → elite
B Rank → peak human
A Rank → Exceptional ability, top 20 to 30% in the school.
S Rank → Outstanding, top few percent (very rare).
Distribution of S-Ranks
Physical Ability: only ~4% of the student body reaches S-rank.
Academic Ability: about ~14% of the student can reach S-rank.
Other categories likely fall between those percentages.
🔢 The Formula (Numerical Conversion)
The Overall Ability Score is not a simple average, but a weighted formula:
Overall abilities score= academic+physical sport+Social Contribution → Only half value (because it's more subjective).

📐 Quantitative → Qualitative Conversion
Each raw Overall Ability Score corresponds to a qualitative rank (E–S).
Maximum cap is around 300 points (based on OAA's design).
Example Mapping (approximate):
0–59 points → E Rank
60–99 points → D Rank
100–149 points → C Rank
150–199 points → B Rank
200–249 points → A Rank
250–300 points → S Rank
