This is an amazing site for IQ testing, it even has a personality test. The CAIT and CORE (both great tests respectively) being free, and some of the Z - Scores for tests being free too (IDK if the CAIT is gonna be free for long though). Its great if you want to do large studies involving IQ/Personality or even both. It also provides g - loadings and reliabilitis, which dont necessarily make it better, but it's cool. Oh yeah if you see those dumb reviews saying "this site is a scam because you have to pay" that's stupid, and quite frankly illogical.

Great tests. They map onto previous IQ tests pretty well (WAIS 3 and 4). The block design is much harder in real life. That is the only section that inflates your score. They would likely need to make their norming publicly available (show the actual distribution of scores). I feel confident that people who take online IQ tests will be about 1 SD above the mean. Any higher than that and people are usually not taking online iq tests. There is also people who quit midway through the exam and start over, with no penalty. This inflates the score. The only issue I have with online IQ tests such as these is that they allow you to restart and to take breaks whenever you like.

Tests were nice, some very specific english wording, which as a non native speaker is a little bit annoying, but overall score was fine. (score is shown with standard deviation at the end, people who complain there is no result at the end probably dont understand what that is)

This was an interesting test quite different to other tests that I have seen. I like the fact that there was a time limit which I think was important.

Took the test, got a result, liked what I saw. 5/5.

One of the most comprehensive libraries of cognitive (IQ) testing resources I have found on the web.

Tests are accurate and recommended by most folks on the r/iqtests subreddit. The only problem I've ever had are with some of the audio tests in the CAIT. The reviews that are all 1 star look to be from the same group of individuals or a competitor. Some of the tests here do require a cost but it is pretty inexpensive compared to some I've seen

Easy enough test to complete, doesn't take all that long but understandably that also limits the specificity of the results compared to the more comprehensive testing you could do with a physiologist. That said, you get told a simple summary once done of your score in deviations above/below the mean. And you can optionally pay for a more thorough breakdown if your results. Overall recommended.
