That can be said for any degree. I've always been amused by those who go to college with no idea what they want to do or major in, but that's me.

You can graduate College with a gpa of 3.0+ and not known a damn thing about your field. You can graduate with an aviation degree without knowing what an Ops Specs is because not one class or one professor exposed the student to what it means to the carrier and it's pilots. The only way you get that kind of education is by asking questions, exploring resources and interning or getting into the field wherever you can before you graduate.

And I think that goes for any degree vs the real field.
