it's important to note that different IQ tests may have different scoring systems and maximum scores.
As for Albert Einstein, there is no definitive record of his IQ score because he lived before the modern IQ tests were developed. The claim that Einstein had an IQ of 160 or higher is often circulated, but it is speculative and lacks concrete evidence. It's worth mentioning that IQ tests measure certain aspects of intelligence, such as analytical thinking and problem-solving skills, but they do not capture the entirety of human intelligence or creativity.
Einstein was undoubtedly a remarkable thinker and made significant contributions to physics. His genius can be attributed to a combination of factors, including his exceptional curiosity, deep intuition, creativity, and the ability to formulate and explore complex scientific theories. It is his groundbreaking theories, such as the theory of relativity, that have solidified his place in history as one of the greatest scientific minds.
