The professional IQ test (a la Mensa exam) asks questions that are not 'what do you know' or 'what historical dates and events have you memorized' but instead, 'can you solve this problem'?

It doesn't matter your age, ethnicity or parental status. That is irrelevant. It is this: How does your brain work?

There will be things like this: a series of numbers, shapes or colors that are offered in some random combination and you have to analyze them and figure out the pattern and then determine the next most likely number, shape or color. There is no place to look up the answer, you have to just figure it out. Either you see the pattern, or you do not.

There are also questions that ask riddles like this: if Person One has 450 widgets and gives 175 widgets to Person Two, how many will Person Three get? The answer may be zero. Because no one has to give Person Three any of the widgets. So, pay attention to the question.

The highest IQ scores will be from people who are good analyzers who notice details, and who possess medium to high math skills with a good dose of logical thinking, common sense and pattern recognitions skills.

Truly, are you able to think and parse out solutions when given a challenge? Or do you fold and choke and draw a blank?

Many good IQ tests are online. Go look and try for yourself. You may surprise yourself with how well (or how poorly!) you do.
