Lol, yeah, the tests online are just for entertainment. @Alaskan, the other scary aspect to consider, is that if you are actually that smart... boy are people dumb.
I did have a longer test done in college, lasted several hours, and placed me at 144, but it's worth noting I was under the influence of several medications at the time. Lots of pattern recognition, and recall testing. I was asked, (almost stalked ) to retake it, once off of medications, but never did.
The test was administered by a graduate student working on her doctorate, but was supervised by a professor. According to professor, based on the types of medications I was taking (tricyclic antidepressant, some other antidepressant, and two kinds of sedative/anxiety medications), my score would likely have been much higher if I was clear headed. I did actually fall asleep during one of the recall tasks, so that probably didn't help.
Based on what I know of myself, I can say with certainty 194, or above is definitely outside my mental capacity.
Now... what kind of a Star Wars character am I? Hmm...
