Assuming you took my advice about the age for your final results, that's very impressive, Azure.
Still, as stated, think of them more as a general indicator. I've found results to fluctuate pretty drastically from person to person once they're past the 110 point on those tests depending on the test, as there's normally questions requiring background knowledge they may or may not have/think about. Similarly, it's quite easy for people to focus on these concepts alone and make their results skyrocket on IQ tests.
And, of course, as people have more or less already stated, most IQ tests focus primarily on basic math concepts and knowledge of the english language, rather than critical thinking, problem solving, artistic evaluation, scientific understanding, and other such categories. They cover a very narrow spectrum.
To throw even more numbers out there, here were my ACT scores from when I took the ACT during my junior year in high school. If you're unfamiliar with the ACT, the absolute max for any category is 36. Take them as you will:
English: 34
Math: 28
Reading: 30
Science: 31
Composite: 31
