A quick look at a major Midwestern US Big 10 university requirement for, say, mechanical engineering:
Mechanical Engineering Requirements
A summary of college requirements for mechanical engineering includes the following:
Fundamentals of Engineering (2 courses)
Chemistry (2 courses)
Electrical Engineering (2 courses)
Industrial and Systems Engineering (2 courses)
Materials Science (1 course)
Mathematics (5 courses)
Mechanical Engineering (20 courses)
Physics (3 courses)
Technical Electives (15 credit hours)
The college requirements total 157 hours of course work. The university requires that students take 35 hours of General Education Curriculum courses which total 192 hours required for graduation.
35 hours at 5 hours per course is 7 non-engineering classes to graduate. But 3 of those are probably freshman English. That means that an engineer is only required to take a whole 4 classes in non-techie stuff outside of English.
Doubt is not a pleasant condition, but certainty is absurd. - Voltaire
