I’m not sure if it’s accurate without a time limit I answered 18/20 (for the newest version it’s not letting me restore purchases)

I think that the test is okay. The questions seem a bit challenging, which is good. However, I’m not entirely certain whether or not this is a valid test or not do to the lack of time constraints, it doesn’t adjust for age, and the fact that only a few people seemed to have downloaded this game so the sample size for the test is a bit small. If nothing else, this is at the very least a decent brain game.

There are several questions I know I got correct and it states I answered incorrectly. It gives you the reason for the answer and will show what you answer. Many of mine show exactly what it says is the correct answer but will say I answered incorrectly. Very disappointing that I paid for something that’s not even accurate!!

I’ve only done the basic test so far, and I took it twice to make sure that what I was seeing in the results section was what I thought I was seeing: the answers I provided were correct, but the results states that my answers were incorrect for several of the questions.
