I doubt that
I took three IQ tests the other night online. The one that seemed the most worthwhile involved pictures only and was 60 questions. It's at
http://www.iqtest-center.com. At first it started out really easy but got pretty difficult toward the end. I ended up higher than I expected myself to be.
IQtest.com sucks -- it's all true or false which doesn't seem like it could be very accurate with a 50/50 chance of being right if you guessed. It's also clearly an affiliate site, but they do send you your score for free.
