10.  The sheets with tasks were prepared based on the Japanese ISHIDO-SHIKI sheets used during the Championships in Japan and the same scoring system was used. This means that students in categories KYU 9, KYU 8 and KYU 7 receive the same sheet, in categories KYU 6, KYU 5, KYU 4 receive the same sheet and students in categories KYU 3 and KYU 2 receive the same sheet.

11.  Students are assessed in their category, i.e. they compete with participants in their category only.

12.  For example, a participant enrolled in the KYU 8 category will receive a KYU 9-7 sheet. His task will be to complete as many examples as possible in a given time. The worksheet contains tasks higher than its level. He doesn't have to do them. The score he gains will be included in the competition from the KYU 8 category. The same sheet will be completed by a participant enrolled in the KYU 7 category and his score will be included in the competition from the KYU 7 category. A student from the KYU 8 category will not compete with a student from the KYU 7 category.

13.  A participant can only take part in one category of the Championship.

14.  The championship takes place in the following stages:

a) Stage I – calculations on Soroban (3 times 5 minutes)

b) Stage II – calculations in ANZAN memory (10 minutes)

c) Stage III – calculations in FLASH ANZAN memory (10 minutes)

15. The winners of the Championship are the participants who score the highest number of points in a given category. The participant can win 1st, 2nd or 3rd place.

16. The deadline for entering the Championship is March 31, 2024 at 11:59 p.m. Applications should be submitted via the website: https://www.arytmetykamentalnamistrzostwa.com/
