Credentials: Took a 4-credit course in  Intermediate Electrodynamics (upper-level college course) during the Spring 2013 semester.<br><br>Having no previous experience with the 3rd edition of the textbook by Griffiths, I cannot comment on any improvements in the current edition. However, I can say this much: Griffiths is very fond of his own notation. Some of it makes sense (like the cursive r=r-r' to denote a relative position vector), while some of the overly formal representation with primed coordinates confused me most of the times.<br><br>Regarding the organization of material, the author does a good job of explaining physical concepts in words, while also showing clear mathematical derivations and examples with nicely explained solutions. The large amount of practice problems varies from plug-and-chug to incredibly difficult, both conceptually and mathematically. I was indeed challenged while solving problem sets for my course, mostly from a conceptual point of view (Electrodynamics is inherently non-intuitive, in sheer contrast to, say, Classical Mechanics). Overall, I would rate this as a very solid undergraduate text.<br><br>PS: I would not recommend this for self-study. This material is pretty heavy and a knowledgeable professor can make things easier! Whenever I skipped class, I found it hard to get back on track. Sadly, that has happened many times...<br><br>PPS: I do not like the fact that there is no answer key! If you are like me and enjoy checking your final answers you will understand what I'm talking about. However, I can see why some professors prefer it this way, because it prevents cheating.
