>>192536In 7th grade, I took an SAT test without preparing for it at all, it was spur-of-the-moment, I knew about it about an hour ahead of time and didn't do any research or anything. I scored higher on it than the average person using it to apply for college in my area.
An IQ test has shown me to be in the 99.9th percentile for IQ. This is the highest result the test I was given reaches; anything further and they'd consider it to be within the margin of error for that test.
My mother's boyfriend of 8 years is an aerospace engineer who graduated Virginia Tech. At the age of 15, I understand physics better than him, and I owe very little of it to him, as he would rarely give me a decent explanation of anything, just tell me that my ideas were wrong and become aggravated with me for not quite understanding thermodynamics. He's not particularly successful as an engineer, but I've met lots of other engineers who aren't as good as me at physics, so I'm guessing that's not just a result of him being bad at it.
I'm also pretty good at engineering. I don't have a degree, and other than physics I don't have a better understanding of any aspect of engineering than any actual engineer, but I have lots of ingenuity for inventing new things. For example, I independently invented regenerative brakes before finding out what they were, and I was only seven or eight years old when I started inventing wireless electricity solutions (my first idea being to use a powerful infrared laser to transmit energy; admittedly not the best plan).
I have independently thought of basically every branch of philosophy I've come across. Every question of existentialism which I've seen discussed in SMBC or xkcd or Reddit or anywhere else, the thoughts haven't been new to me. Philosophy has pretty much gotten trivial for me; I've considered taking a philosophy course just to see how easy it is.
