And 221 is just about physically impossible, must've been a fluke. We've all seen your picture Ashar, you have a perfectly normal sized head and brain!

I think 200 is the max possible on most IQ tests. That doesn't mean someone can't hit the ceiling on the test however. There are other tests that can map out the abilities on someone higher but they usually look at more specific areas of ability and don't measure the whole spectrum like a normalized IQ test would.
Age is a humungous factor in IQ calculations-not so sure about gender.
Yep, a real big factor considering that your IQ is the difference between your chronological age and your mental age. MA/CA * 100 = Intelligence Quotient.
For example if an 8 year old answered questions correct for a 14 year old then his IQ would be 14 (mental age) / 8 (chronological age) * 100 = 175 or an IQ of 175.
Gender is only important in how the test is compared across gender lines. Men and women have different areas of competency. Men tend to score higher in the spacial areas while women tend to score higher in the verbal subtests. This in no way however can be interpreted that one is superior to the other no matter what any of my girfriends may have told you.

All that aside however I personally don't hold a lot of stock in IQ tests as a measure of function for the simple reason nobody has yet agreed on what
intelligence is.
Current tests such as the Weschler and Peabody tests for adults and children seem to measure the person's ability to succeed in a middle class school environment but some people who score low on that measure will often succeed despite the score and vice versa some who score high end up going nowhere.
A fellow named Terman did a study of hundreds of children who scored 175 and above on IQ tests. He followed them for 30 years and at the end of that time none of the now adults had achieved beyond what could be expected of a normal motivated adult. He did find that they were a little more adjusted and earned a better living than controls but none were identified as genius material.
A lot of researchers are beginning to look at other things than have previously been included in IQ tests. Things such as musical intelligence, spacial intelligence and kenesthetic intelligence and these are only some of them. One proposed theory identifies as many as 100 differing intelligences.
Thus since nobody can positively tell what intelligence actually is it's obvious that IQ tests are only aptitude tests and not a full measure of the intellectual worth of anyone. The best use hoever isn't in the actual score or quotient but in what the sub test scores tell about a person. These have been used for some time by psychologists to map out a person's brain and pinpoint specific abilities and diagnose disabilities. For that the IQ test is a very powerful instrument.
I've got a great new theory about these online "so called" IQ tests... they're there to find out how many idiots online will try them

I happen to know my real IQ according to proper tests

I've always suspected that myself. Seems great minds think alike. ;)
