According to the biographer, Einstein was "slow-witted" when he was young, he often failed in mathematics, and his Greek and Latin were also poor. However, according to the data, although the genius had poor language skills when he was a child, he studied well and was a child prodigy. He always gets high marks in Greek and Latin classes, and even gets full marks in math every year.

It turns out that the biographer made a mistake about the level of the school at that time. At that time, Einstein went to primary school in Arau, Switzerland, and the school adopted a six-level scoring system. One point is the highest and six points is the lowest. Einstein scored one point in mathematics over the years, which is the highest level. But when Einstein 16 years old, the scoring method was changed to the highest six points and the lowest one. Therefore, biographers regard the highest level as the lowest level when looking up Einstein's early school achievements. Therefore, Einstein's "childhood dullness" has been handed down.
