Yuu is a bit special, but I think his issue is largely trying to do things the way a genius would, when he is far from one. This chapters shows it pretty well, the girls are pretty shit at teaching him anything because to them it's just a matter of "feeling it". If he was following the example of some mid actor, rather than a top-tier one, he would probably do better (not awesome, but better).
I assume the entire message of this arc will be that trying to measure everyone by a genius' standards is absolutely myopic, and that, if fostered properly, even a mediocre person can make something of themselves, even if they will never fully close that gap.
