Offer a wide range of tests and several full scale ones. Even the one which are not fully free let you see your IQ (you just don't get the full explanations but you have the figure at least)

The tests on the website are excellent and are useful in understanding personal cognitive abilities. Just as importantly, the CognitiveMetrics team is stellar. After I had technical issues with accessing data from a particular email, they were prompt in responding to my messages and delivering me a solution.

After taking their 1926 SAT, for some reason, my scores didn’t save to my profile. However, the staff at CM were incredibly helpful in retrieving them for me.
