Maybe it is only the intelligent ones who allow the results to show !
I did the test, you get a lot of time to work out the answers ( eg which of the following words cannot be found in the word. XXXXXXX - you can easily work it out if it isnt obvious to you). I personally found the questions easy - the number sequences were obvious and the picture sequences were easy to follow.
If I had only got 50% I wouldnt have posted the results to my profile though !
