I have the same pattern; and it really does distract me from my schoolwork, and from conversations with other people, which often get boring (and speech is such a slow way of communicating anyway).
But it even happens when I'm doing things I enjoy that just happen to have mildly boring parts--for example, leveling on "safe" monsters while playing an RPG. I don't know how many times I've died because my mind was off in la-la land, and I let my HP get so low that I get killed by a sickly rat or something else equally humiliating.
It's even happening right now, while I'm typing this post.
Lately I've been experimenting with caffeine pills (200 mg every 4 hours), and these seem to give me a little more focus.
I really do suspect ADHD at this point... or at the very least, ADHD-like symptoms caused by depression. The only thing is that my depression is fading, controlled by medication and counseling; but the ADHD-like symptoms are still there.

A child who reads both french and English and memorizes poems at the age of four CAN'T have ADHD...
...unless said child also has a high intelligence, allowing him/her to pick up those poems just from having listened to them once or twice. ADHD and giftedness are often closely associated. (And besides, learning two languages before you are four is easy enough to do--young brains are so very suited to learning language. Reading that early is probably typical Aspie hyperlexia. Do you perchance have an aptitude for languages today?)
I had straight A's during my elementary days, and one or two B's total during high school; this wasn't because I knew how to study, but because, when I sat in class, the teacher only had to say things once, and I'd pick them up--even while daydreaming about my current special interest.
My thoughts were always so much faster than the world around me... only a very small part of my mind was actually needed to pay attention to the teacher. The problem is that, now that I'm in college with my intellectual equals, I need to pay attention to a higher degree than I used to when I was a child--but I don't know how. Not to mention that, when you are intelligent and just "pick things up", you don't learn a thing about how to study when you're not intensely interested in something...
