I used to do math olympiads in high school and the concepts I saw there were always something I hadn't seen before. I always used inner monologue to figure out solutions though. I had never practiced much for math olympiads, I performed relatively well for my area, not good enough to make it to international levels though.

I can't follow verbal instructions as well though, I couldn't listen to the teacher etc. But I think it's because my inner monologue takes all the focus so I just follow my inner monologue which is probably completely another topic than what the lesson is about. I can't really focus away from my inner monologue. When I try, then I would just have philosophical meta discussion about my inner monologue. But also this meant that I couldn't actually learn the subjects as well during the class. I either had to learn from my free time or not at all.

Also have to watch films with subtitles, because audio language I have troubles focusing on.

I think all I have is my inner monologue, no good visual imagery, or other types of "thinking". I think makes me really poor at navigation as well. I never remember how to get somewhere. And also in general for anything 3d, like 3d games I will perform bad at, awareness wise.
