Musk: some people have talents in different fields.
Most people can't act well, so is it correct to say that a degree at NIDA is harder than engineering?
I'm sure you wouldn't be able to critique a piece that is prescribed to someone for third-year English at uni, as I'm sure they wouldn't be able to do a complex maths equation from third-year Engineering.
At the same time, you have no concept of how hard intermediate and third-year economics can be. In fact, go take it, then get back to us. Hell, take some third-year marketing and if you get above a credit, I'd be very impressed.
In summary, how hard something is, is relative. Considering most engineering students spend their first year drunk, I doubt that first year engo is difficult. Neither are first-year accounting, or economics.
