This ranking system is based on the official examination structure used by the{' '}
|
||||
<strong className={css({ color: 'white' })}>Japan Abacus Federation</strong>. It
|
||||
represents a standardized progression from beginner (10th Kyu) to master level
|
||||
(10th Dan), used internationally for soroban proficiency assessment.
|
||||
</p>
|
||||
<p className={css({ color: 'gray.300', lineHeight: '1.6' })}>
|
||||
The system is designed to gradually increase in difficulty, ensuring students
|
||||
build a solid foundation before advancing. Each level requires mastery of
|
||||
increasingly complex calculations, from simple 2-digit operations at 10th Kyu to
|
||||
30-digit calculations at Dan level.
