All these kids go to school too (though here it's still only 4 hours a day, which I am envious of) and from tutoring a number of them in English I can attest to the fact that the kids in my neighborhood are very 'book smart' too. It might surprise people not from here, but nowadays everybody in Phnom Penh has tablets and smart phones and they spend a lot of time on those learning. Intellectually they're more than capable enough to succeed in higher academics, but financial difficulties may limit some of them.
