Well... there's nothing to be surprised about; I would also like lessons to be 40 minutes long, but we only have that twice a week. Regarding the uniform: it seems they introduced it in many places, and in the first month, they went around and checked, and gave negative marks to classes... But what's the point? After each such visit, the classes had -12 points... So they gave up on that idea.
And now, the director has changed, and there's a new, strict one.
But even she didn't try to introduce a uniform; she only tried to make the dress code officially business-casual.
