Not too easy. Not too difficult.
Moberly is one of the most dedicated professors I've ever studied with. He created study sessions outside of class before tests, even going so far as to bring pizzas to the students who were studying. He expects you to help yourself. You have to be motivated in this class. As long as you put in the time and do the homework (rather than copying it), you'll do fine.
This course was more math. I personally like math, so I thought it was great. It was Differential Equations, so that's what you learn. Fourier series, convolution, time domain vs frequency domain, etc.

Advice for students:
I made "memorize pages" the night before exams, then memorized them the morning of. It worked out great for me. Moberly doesn't give you a formula sheet for anything except the transforms, so memorizing formulas is a must.
