(I''m not the OP.)
I have a degree in English, and another one in mechanical engineering.
The 9 English classes that I took were uniformly less difficult and less rigorous than the 25 or so engineering classes I took. When I studied English, I already had a reasonably well-developed understanding of logic, but it was not used in my English classes. I would estimate that I could have earned a B average in English with 5-10x less time spent than in engineering. Standardized tests suggest that I have more aptitude for engineering (or at least math), so English should have been harder for me if the curricula were of the same difficulty.
