Common Regulations
for Abacus Calculation |
※ The number of questions is 15 for each class and subject. The limited time is 7 minutes. (For the test of the Level grade, 30 questions.)
※ Out of 15 questions for the test of addition & subtraction, 7 questions will be for addition only and 8 questions will be mixed with addition and subtraction. The minus(-) numbers will be included evenly as follows : 1 minus number for 3~4 lines, 2 minus numbers for 5~7 lines, 3 minus numbers for 8~10 lines.
※ Grading Criteria : 10 points will be given for each question of all the subjects (add/subt, multiplication and division), and 100 points are the passing grade. For the test of the Level(段), the passing grade is 100 points for Level 1, 120 points for Level 2, 140 points for Level 2......300 points for Level 11.
※ For the higher grades than Class 3 in multiplication and division, round to the nearest 1000th (round-off at 4th decimal) in the denominative numbers, and round to the nearest whole number (round-off at 1st decimal) in the abstract numbers (7 questions of denominative numbers, and 8 questions of abstract numbers.)
