What is an IQ Test?
---------------------------------------------------------------

An IQ test shows how "intelligent" you are compared to other people. But intelligence is not a clearly defined term – it is simply what an IQ test measures. That's why only results of the same test can be compared: it tells you whether you solved the tasks better (above IQ 100) or worse (below IQ 100) than the average. So don't take your IQ too seriously – see it as an exciting comparison with others!

The problems with this app are as such: 1. It does not provide an accurate score. The score that it provided was around 30 points off my actual score. 2. It is ridden with ads. An ad pops up every ~30 seconds. 3. Said ads appear during the test! That does not make for a good and accurate testing experience. If you are distracted by an ad for a mobile game, it is going to distract you. In fairness, the developers of this app only care about money, not remotely accurate results.

this was pretty challenging but it should counter your level of english in the result. I've got french as native language, and I still learn about english so even if it was more challenging, there was a bunch of questions I'm not sure I have understood. but thank you for this app, it is fun! also, could be interesting to have a result on exercise mode. //please, if you question your iq don't start with this//

Some of the questions don't really make sense, & you'd think that given it is an IQ test, it wouldn't be written in pigeon English & would use the correct grammar. The ads are a nightmare. I can't understand why or how exactly you earn the points or what the point is in them. However, it is a good way to keep your brain active & to pass the time. It's frustrating that you can only see the answers if you pay. I'm sure some of my answers were definitely correct. I just refuse to pay to find out.
