+1000. As an undergraduate, probably the hardest class I had was Quantum Mechanics because it is really important to get a good teacher - you have to learn to think very differently from classical mechanics and my instructor wasn't very good.
In grad school, as a EE major, the hardest classes I took were Solid State Physics II and Electromagnetics using J.D. Jackson as the text. It is one of those things like being in military combat - it is not easy to describe how tough it is but everyone who has done it will nod in agreement.
