To address this pressing need, in 1904, Binet, along with his collaborator Théodore Simon, developed the Binet-Simon scale. Unlike traditional academic exams, this pioneering test did not primarily focus on reading or writing skills. Instead, it featured a series of tasks that assessed various cognitive abilities, such as problem-solving, attention, and memory. The underlying principle was to gauge a child’s innate learning potential rather than the knowledge they had already acquired. These are considered numerical logic questions and while some may be simple, others can be very tricky.

Alfred Binet developed the first practical intelligence test in 1905 to identify French schoolchildren who needed educational assistance. The modern concept of Intelligence Quotient (IQ) was later introduced by William Stern in 1912, representing the ratio of mental age to chronological age, multiplied by 100. The digital test evaluates general cognitive performance using standardised scoring methods commonly applied in intelligence assessment. An IQ test, or Intelligence Quotient test, is a standardized assessment designed to measure human intelligence. It evaluates a range of cognitive abilities, including logical reasoning, problem-solving, numerical aptitude, verbal comprehension, and spatial awareness.
