If it helps, I was told IQ tests can't accurately measure the IQ of people with Autism/Aspergers Syndrome. I'm assuming you have one of those. If not, then I guess this isn't helpful. I was told this when I was tested just before my first week of university, to see what extra support I would need due to my disabilities. Apparently IQ tests test 4 specific areas: communication, maths, spatial-awareness and logic. People with neurotypical (have I spelt that correctly?) brains have roughly the same amount of knowledge in all 4 areas, which is why the IQ test is more accurate for them. People on the Spectrum have a very great understanding in one area, though the area changes depending on the person. However, they have average or below average understanding in other areas. So they might get all of the communications questions right, but only half of the questions that test other areas right. So their IQ will average out on the test to average or below average counting all areas. So it will be inaccurate in measuring intelligence. For example, I scored very highly on communication, but my IQ is between 98 and 130 depending on when I take the test. I know this because I've taken several of them over the last few years. Obviously a margin of error like that is a strong indicator that the IQ test is useless for me. Probably you too. I think that if you're intelligent then you'll know it. You'll understand a lot of things to put it simply. That's what has happened to me anyway.
Even for neurotypical people, I thingk an IQ test is just the least worst way of measuring intelligence, rather than the best. Many people without "Book smarts" are streetwise for example. Some people are good at working things out almost instinctively, but can't recall most of what they learnt in school. Some people "Think on their feet", but some people aren't good at that. There are different types of intelligence. Also, there are books which were written specifically to teach you to improve your IQ score. Guides to how to pass an IQ test with the highest possible IQ possible. If you can learn how to do it in this way then they don't measure your intelligence alone. They also measure how hard you've studied the guide book, and how good you were at remembering it. It?s not a true test of something already implanted, or whatever term you want to use, in your mind.
IQ seems to be dished out randomly anyway. I read a news story about a 2 year old who had an IQ of 142. That's well above average but her parents had more typical IQ scores, and she hadn't been to school yet. So her IQ wasn't earned and probably wasn't genetic. As far as I can tell, IQ is either a cosmic accident or fortunate genes. I also think that what you do with the IQ level that you have matters more than what the level is. People put far too much emphasis on it. If you're smart people will know it. Me for instance, based on reading your posts. They won't need to know your IQ in order to work out how intelligent you are, though I can understand why a lower IQ test score than you were anticipating would seem shockingly unpleasant at first.
