### Levels, Scores, Winners

Olympiad Participants will compete against their peers (the same age group; 4-6, 7-8 or 9+) at the level they are registered (beginner, elementary, intermediate, upper-int or advanced) in two skill areas (**Number Chain** and **Anzan**) in addition and subtraction.

**NUMBER CHAIN** Exams

All participants are expected to enter their answers as fast as possible and solve as many problems as possible in the given limited time. The time limit is 4 minutes (240 seconds) for addition and subtraction exams and 3 minutes (180 seconds) for multiplication and division exams. The maximum limit for wrong answers is **three**. That is, a participant can continue the exam till the end of the given time even if he has made 3 mistakes. But, one more mistake will cause the exam to stop at that point and the participant's score will be the number of correct answers up to that point. The highest achievers will be those who produce the highest number of correct answers. The competition is based on accuracy and speed. For this reason, participants are expected and encouraged to make calculations mentally. However abacus is not forbidden to use.

**FLASH ANZAN** Exams

In this exam, numbers will flash and disappear on the screen one after another with a certain speed. Anzan exam will have a time limit of 5 minutes (300 seconds). The difficulty level is preset for each level but the speed is to be adjusted by the participant. There is a preset difficulty for each level that starts with easier problems and moves to more difficult ones at each round of 3 questions. Only one mistake will be tolerated at each round. So even if a participant gives wrong answer to one of the 3 questions at a certain round, the exam will continue to the next round of 3 questions where one mistake will again be tolerated. However if there are two wrong answers at a certain round, the exam will stop at that point and the participant's score will be the number of correct numbers up to that point. There is also a limit to the number of rounds with one mistake. This limit is six. That is, a participant can continue Anzan exam 6 rounds (18 questions) even if he makes one mistake at each round of 3 questions. But if the number of wrong answers exceeds 6 at a point before the time is over, the anzan exam will stop at that point, and the score will be the total number of correct answers up to that point. So it is critically important for each participant to adjust their optimum speed that will allow them to go with their maximum speed and maxmum accuracy

**WINNERS** (Top Places)

There will be three top places (First place, second place and third place) at every category. Let's take 4-6 age group and list the top places for all categories.

Beginner: (Number Chain) 1st, 2nd, 3rd (Anzan) 1st, 2nd, 3rd

Elementary: (Number Chain) 1st, 2nd, 3rd (Anzan) 1st, 2nd, 3rd

Intermediate: (Number Chain) 1st, 2nd, 3rd (Anzan) 1st, 2nd, 3rd

Upper-int : (Number Chain) 1st, 2nd, 3rd (Multiplication) 1st, 2nd, 3rd (Anzan) 1st, 2nd, 3rd

Advanced: (Number Chain) 1st, 2nd, 3rd (Multiplication) 1st, 2nd, 3rd (Division) 1st, 2nd, 3rd (Anzan) 1st, 2nd, 3rd
