The online tests are worthless. A true IQ test is a lengthy process that involves a number of different types of questions and scenarios. The test is administered by a trained professional, timed, and OBSERVED. Some parts of the test require tester-testee interaction... Tickle, for example, is absolutely worthless.

If you are stating a score you got from Tickle or something similar, forget it...
