My son is going to Embry Riddle Aeronautical University in Prescott AZ. They have modified their classes to a point where they are not actually using the CNC machinery in a class (it's a mechanical engineering degree). Instead, instructor does some work, then the students write about it. He knows he's getting a lesser education but what can you do? We suggested retaking the class at a later time but that didn't work for him for some reason or another. Weird times.
