What are the “Levels” mentioned above?
Twenty levels for mental math were clearly defined to indicate the ability for a person to correctly answer arithmetic questions in a given time. The levels go from Level 10 (the easiest) all the way to Level 1 followed by Level Pro 1 to Level Pro 10 (the hardest). The standardized system has been well recognized and widely used in many countries for issuing certifications according to results of official exams. IQ Abacus Math School students will take certification exams conducted by the US Mental Math Federation. Please refer to http://www.USmental math.org for details.
