This test estimates your IQ score quickly using an adaptive algorithm. The questions are drawn
from a large pool of professionally validated IQ test items, such as from the Otis Gamma,
a cognitive performance assessment famously used to test various US presidents, including John F. Kennedy,
Richard Nixon, and more. The Otis Gamma was a group-administered test designed to identify individuals
eligible for Gifted and Talented Education (GATE) programs for primary and secondary education.
