I am a teacher and I’m well aware of what you’re talking about. There is so much more I want to adress, but there is only so much time in a semester. You cannot accomodate every level of experience simulatiously, so you tend to go for the lowest common demoninator.

A good school teaches you the basics of programming, best practices, frameworks, basic tooling and probably more. A school, good or bad, can not make you a good programmmer. You have to make yourself a good programmer.
