When the teacher asks you to design a class hierarchy and after a week designing he comes and says "You know what? We'll work with a design a I made" and throws your design to the trash

That's a GREAT teacher right there.

He/she is obviously preparing you for working conditions in a real world company.

Of course that's probably not what they were *trying* to teach you ... but life is full of all sorts of lessons!

@mhall yes it is!
