The IQ test you have done is an evolution of Raven's progressive matrices concept. It measures the domain of general intelligence: it measures logic, the ability to reason clearly and to grasp complexity, as well as the ability to retain and reproduce information patterns, sometimes called reproductive capacity.
Above all, take into consideration that the average of the standard IQ is set at 100 for historical reasons. The test that you have passed is designed so that the average result of the candidates is 100. Then each candidate, according to the result that he obtains, can compare his result to the statistics of different parameters.
Based on the results of the test you just completed, your IQ score is 99.
This IQ score is an estimate. Your score may change depending on your form and the conditions under which you take the test.
