Highly recommended is the World Intelligence Network IQ Test Center, where more than 580 IQ tests are presented. Each one of the IQ tests dedicated page includes a short description of the test, a working link to the test homepage and information about the type of the test (spatial, numerical, verbal, mixed), fees, supervision and time requirements.
