I remember doing the tv ones years ago here in britain. The 2nd made me realise it was all a bunch of crap. Why? Because one section asked you to look at a series of distorted pictures of celebrities and work out which celebrities they were. This meant you had to recognise who these people were, which is not testing your intelligence at all if you simply don't know who these people are.
Also the last question was a series of upsidedown faces, with one of the mouths on one face turned upsidedown again. You were supposed to look at the faces and figure out which face had something wrong with it. I immediately knew what it was they were trying to get at and simply turned my head to the side so I could pick it out. Literally anyone could get that question right, it's not testing intelligence at all, anyone who has seen that illusion before knows what it's about and figure it out.
I still somehow scored higher on this one than the "easier" one from the previous year though.
