The Interrobang‽ High Range IQ Test by Dr Jason Betts
Welcome to the ‽ High Range IQ Test by Dr Jason Betts. There are 16 items with 16 different answers.
See the Score and Norming Data File at www.psiq.org/lux for the submission instructions and guidelines.
The use of the internet and all reference materials is recommended to research all terms not fully understood.
Find the answer that is simple, obvious, satisfies the greatest number of clues and has the simplest complexity.
Every item has a one character answer, which is a letter (LE), symbol/figure (SF) or punctuation mark (PM).
This test is designed such that all answers are visable on keys on a keyboard plus one other common character.
