IQ test results!

I recently took up an IQ test at testQ.com and the results were quite interesting to read. Here's what the test engine said:

Precision Processor

Your IQ Score is: 136

You've got a very experiential way of learning and a strong mathematical mind. You're able to whittle even the most complex situation down to comprehensible component parts. In short, you have mastered the art and science of precision. That's what makes you a Precision Processor.

For you, life is a series of equations. Your brain is naturally predisposed to intense mathematical acuity, and your understanding of numerical problems is unparalleled. It's second nature for you to cut to the heart of an issue, so that you can discover quick solutions to problems while others get bogged down in unnecessary details. One Precision Processor that comes to mind is the Greek philosopher-mathematician, Pythagoras. Pythagoras had a mind for numbers and, as such, could come up with previously unknown theories like his method for calculating the sides of a right triangle (a2+b2=c2). You too, can use numbers to translate aspects of the world around you — something that doesn't come easily to everyone. Your quick mathematical mind will allow you to communicate a variety of ideas to other people, so don't keep it to yourself.

Precision Processors can apply their mathematical skills to any situation involving numbers. That's a talent that will come in handy for everything from the workplace to splitting a bill 12 ways to converting foreign currency in your head. Others often look to you to do the math and luckily, you're well equipped.

My opinion: Pontificating on these results, right since 2003 when I started taking these tests, I almost landed up in the same region of score - between 129 - 136. I am amazed that I always get a score around this number but not more or less!! This brings me to the trillion $ question - Does IQ get shaped by environment or does it remain the same for a person due to genetic reasons?
