Now That's an IQ Test!

The other day, I stumbled across an invitation to take a free online IQ test. I usually ignore these sorts of clickbait ads and invitations but having nothing better to do at that moment, I indulged.

The test seemed fairly standard. My only complaint would be that it dragged on a little too long. Still, it did contain a few challenging problems. As I neared the end, I became curious about the questions I may have got wrong. 

A big red button appeared on the screen after I completed the test. The text within the button informed me that I had achieved a remarkably high IQ score, the details of which the testing company would be happy to share with me for the low price of seven euros, but only if I responded within five minutes.

After that, the fee would increase to twenty euros.
