Can’t get enough of those brain teasers? The Ultimate IQ Test Book may just help. It is a great resource freely available on the internet which includes a whopping 300 pages of IQ Test practice questions. These tests would be great not only for the daily brain teaser to keep our neurons firing, but also as a mock practice test for the big day when you buckle down and take a real PhD-Certified and calibrated IQ Test such as our Free IQ Test.
Have any of you used this resource? If you have used a resource such as this and then taken our IQ Test, please post your results as a comment. It will be very interesting to track whether those who use an IQ Test practice resource would actually score better on the IQ Test than those who had not.
