You should know that the whole idea behind IQ intelligence quotient is an old theory. It is rejected by most modern educators, neuroscientists, psychologists etc. the truth is much more complex. The brain is much more complex. The whole idea of IQ is that intelligence or the ability to learn is easily quantifiable-take one test, get a score, it will tell everything. In the 1950's when a lot less was known about the brain, this seemed logical.
Knowing what we know now, it is completely illogical. How could one test or one set of arbitrary standards, whatever tell your capacity to learn? For instance, who has more capacity for learning, a computer tech who takes to programming or a ballerina who can recall and execute every single step and movement in an entire 3 hour ballet? (It's not muscle memory.) both are extremely difficult to learn.

IQ tests and the idea of IQ are still used because they are simple, easy, and locked in the public mind as having great validity. The truth is they don't.

So much of what people consider intelligence or talent is really hard work in disguise. For instance, my sister is well known for her work in a part of computing and computer science that is considered cutting edge. Many people say she in incredibly intelligent and has a great talent with computers. I love my sister what she has accomplished with very little outside help is amazing. But I grew up with her. I remember her trying to learn the program on night's so late my mother threatened to pull the computer plug out of the socket, so she would sleep. My sister wasn't necessarily a natural at computer programming. So what? she worked really hard and far surpassed any of her classmates in programming class.

I got better grades than her in school. I have a higher IQ (which is meaningless). I have never been able to learn in depth computer programming. I don't want to do the work to master it.

What I am trying to tell you is really you seem to be obsessing about something that really doesn't mean anything. Comparing yourself to others in any way, you will fall short, because you will never know their whole story. I have gotten to a point in my life rather than competing with my sister, I am proud of her. I am proud of me too. Different lives, different paths, different accomplishments.

I hope this helps in some way.
