IQ testing!

I recently took an IQ test for extra credit in my psychology class. It was a really interesting experience and I encourage anyone who has the chance to take an IQ test to do so. I went to the library and took it one on one with a graduate student who was testing undergraduates for her research for her major. I was kind of nervous at first, however, after a while you become more comfortable which makes testing a lot easier.
The test has multiple sections, some of which are timed. The first section was all vocabulary and took roughly ten minutes. The following section you were given 4 to 7 tiles with pictures on them and had to arrange them in chronological order. There was also a timed math section which was somewhat nerve racking because you weren't provided with a pencil or paper, it all had to be done mentally. There were many other sections, these were just a few examples. The testing can last anywhere between and hour and half to three hours, it took me about and hour and 45 minutes. They grade you based on your mental age, divided by your chronological age, multiplied by a hundred. I'm still awaiting my scores, hopefully I did well!!!!
