I was great in class (unless I wasn't interested, in which case I was at least silently doodling). I just never did get the hang of "doing my homework"
I confused so many teachers. Talk well in class, turn in zero homework, cry, have a backpack and desk just absolutely stuffed with loose paper, get an A on the test anyway, somehow pass??
Real story, I was failing Algebra II. Because, again, I never did my homework, and math was the worst. My teacher told me to get a tutor. I hired a friend to tutor me for a few weeks. On the final I got the highest grade in the class and could tell my teacher wanted to murder me
Anyway if this sounds like your kid, get them in for ADHD testing. They may have "inattentive" type ADHD, not the hyperactive kind. I have not been formally diagnosed but I have strong suspicions
I make jokes about being lazy, but especially as a kid, it wasn't a conscious decision on my part. I just...lost track of things. Papers, reminders, time. I was always convinced I would somehow, miraculously, get my homework done before class. In some nebulous "later"
And sometimes that worked! I once wrote a 10-page paper in the two hours I had before class (in high school) and still somehow got an A on it. But high school was where this stopped working so well too. As my class work got harder, I couldn't bullshit my way through.
College was when the wheels really came off. Add undiagnosed severe depression....yeah. It wasn't a good time.
