To check your IQ, you can take an official, professionally administered test (like WAIS) for the most accurate score, or try reputable online versions (like Mensa's challenge, 123test, MentalUP) for a good estimate, focusing on problem-solving, logic, and pattern recognition, understanding that online tests are less reliable than professional ones.

What was Albert Einstein's IQ?

Albert Einstein never took an IQ test, so his score is unknown, but academics estimate it was around 160, a genius-level score, based on his groundbreaking work in physics, particularly his "miracle year" of 1905. While some speculate it might have been higher, around 180 or more, the 160 figure is the most commonly cited estimate, though it's important to remember these are just educated guesses from his achievements, not actual test results. 

Are online IQ tests accurate?

No, most online IQ tests are not accurate or reliable because they lack professional development, proper administration, and comprehensive assessment, often inflated to encourage engagement, though some reputable sources like Mensa offer limited free tests for fun, while truly valid measures require a psychologist and standardized tests like WAIS or Stanford-Binet.
