Stop me if you've heard this one: an okay, not-great, semi-engaged student is called out by teachers by not "working to potential." Except that kid, in their spare time, is doing amazing things in whatever area they have a passion for. Truly incredible output, whether it be music, video, skating, or, yes, technology. But of course, that's not what the classroom gives a crap about, so the school thinks of the student as average.
I was that kid, and I bet more than a few of you were as well.
