Okay, this is going to sound like bragging, but you asked.
I was the topper in my school (and eventually the highest scorer in my state in a standardized exam), and a topper in my college. When I took an IQ test that measured IQ between 0 and 160, I was told that I needed an advanced test to find my true IQ as the test gave perfect results.
I used to be super arrogant about all of this but have since realized that life isn't about intellectual masturbation. A person's worth isn't defined by their intelligence. Being kind and loving is more important than being a pompous prick.
For anyone who's curious to know how it feels, I can talk about it.
There's the raw intelligence that usually makes connections in my head about people, events and ideas via intuition. I'm good at coming up with unusual solutions to problems.
I've tried to shape much of the raw intelligence into tools for daily use. For example, I'm good with conversations. I have high empathy, and can imagine the dozens of directions a conversation could go as I'm having it. When I was younger I had the penchant to use this predictive ability as a game (Let's see if I can get him to say this by saying this) but have since realized that's messed up. Now I use it to try and avoid subjects that will hurt people. If I know that an innocent subject will eventually lead to an unpleasant one, I'll pivot from that. I also use the ability to present my ideas in the most effective language possible (depending on the person I'm talking to.)
Beyond that, I learn new skills very quickly. In school and college I was good at all the subjects offered without much effort. Effort and motivation have in particular been an issue. If I see a task as easy I really don't feel like doing it. But a challenging task draws my complete attention.
There's more, but every time I talk about this people think I'm an arrogant ass, so I'll stop.
