I think I fall in this category. I was a grade A student until after I dropped out of the gifted program. Some pretty evil teachers, there. Not making this up, I was forced out. Stopped caring about school, but still managed to pass with decent grades because I could absorb things like a sponge. Never studied but passed most of my tests.

I, too, could play any instrument put in my hands. Taught myself bassoon in high school, and was first chair by sophomore year. Always loved art. Still do, but now I'm afraid to start anything because if I don't finish it all at once, it usually never gets finished.
