Hi, I'm posting on behalf of my friend, my kids are still much younger so my insight is limited. Her 15 y.o. son is very capable academically but a recent parents' evening revealed that he just won't do more than the bare minimum. There are 2 or 3 subjects that he does well in and those are the only ones which he gives proper focus to. His behaviour isn't a problem, he's not disruptive, etc but has no zeal.
She's tried heart to heart conversations, she's read him the riot act. Anyone got any tips or advice please?
