Common Regulations
for Mental Arithmetic |
※ The number of questions is 20 for each class and subject.
The limited time for Class 12~8 is 5 minutes, and for Class 7 & higher is 3 minutes.
※ Out of 20 questions for the test of addition & subtraction, 10 questions will be for addition only and 10 questions will be mixed with addition and subtraction. The minus (-)numbers will be included evenly as follos : 1 minus number for 3~4 lines, 2 minus numbers for 5~7 lines, 3 minus numbers for 8~10 lines.
※ Grading Critera : 5 points will be given for each questions of all the subjects(add/subt, multiplication and division). and 70 points are the passing grade.
※ All the subjects of addition/subtraction, multiplication, and division are with the abstract numbers, and the integer only without any round-off in the end.
