I programmed games on my calculator, wrote stories and poems, printed out stories to read in tiny 4pt font so the teacher wouldn't notice, and constantly doodled drawings to keep my mind occupied. I sometimes think I learned more doing that than I did in school (at least until college, which was like a brutal wake-up call I wasn't prepared for).
Honestly I think the worst part is when teachers would get annoyed that you weren't 'paying attention' and force you to stop doing the crap that's keeping your mind busy and 'focus on school', even though you already get pretty much straight A's.
