Excellent for getting the mind working....

However, as a few others have stated, I dislike the repetition of questions. I feel as though a larger database of questions is needed. Alternatively, perhaps the developers could update the questions to keep it fresh and challenging.

As with most other reviewers I too feel that I'd like to know which questions I got wrong, I wouldn't like the correct answer though.

Finally, it would be nice if the bell curve indicating where your score lies is updated. Having done the home test and gotten my mark, I found that this did not correlate to the mark or percentile stated in the app or on the Mensa website. The unexplained inconsistencies make it difficult to truly gauge whether it might be worth taking the supervised test.

Overall, it is a fun app to keep the brain working during those times of boredom, frustration or in my case insomnia 😂

Really good

A really good app for training your brain. I totally disagree with all the other reviews saying that the answer should be shown after every question. The reason for this is because it is like a proper exam. When you sit one of those, you don't know if you got it correct or not until it has been marked. The questions are difficult in places and it makes you feel as if you've just payed for an app that is for a quiz genius. However, sometimes you can find them easier. Overall, I would recommend it and it is defiantly worth the money.

Mini Mensa fun app

This is quite good training if you are thinking of taking a real Mensa test . But don’t get too excited by high scores here as there are limited questions and an unlimited amount of times you can retake to improve your score . You will see questions you have answered before quite regularly and providing you had worked out the answer before you now can answer faster .
