But how do you know? Have you also majored in Electrical, Mechanical or Chemical Engineering so that you can compare how difficult they are compared to English? If not, then I don't think you're in a position to judge, are you?
How do I know that English is not as tough as Engineering? Because all the English majors that I knew in college got drunk and partied every Thursday, Friday, and Saturday night, hardly ever went to class, never studied, and had time to take on part-time jobs, and still got good grades. All the while I spent almost all of my waking hours studying Thermodynamic, Partial Differential Equations, Vibration Theory, Fluid Dynamics, Heat Transfer, and all the other Mechanical Engineering coursework, either in the library or in my room. When I got to graduate business school, everyone said the same thing about their undergraduate colleges, that the English majors partied all the time while the Engineering majors did nothing but study all the time.
