## Main Question or Discussion Point

Hi, I've posted here several time because you all gave me very helpful suggestions. Let me recap briefly my situation. I apologize for the very long post.

I have BS in chemical engineering but now I'm going through a MS degree in nuclear engineering. Although - given my background - I should have gone for nuclear plants management, I decided to switch to the "theoretical side" of nuclear engineering (reactor physics, plasma for fusion applications and so on...). Although I'm struggling a lot I managed to get very good grades (also thanks to you ) in mathematical methods and reactor physics courses.

My main problem is the lack of preparation in EM. When I started my MS degree (last September) the only EM I knew was "high-school" EM (I didn't even knew maxwell equations). I went through Griffiths' book during this seven month and I'm currently at chapter 9 (waves). I forced myself to do 10/15 exercises per chapter (I know the number is not much, but I'm self studying while attending other courses... time's limited ). I loved Griffiths' book, but now that I know something (not much, but I definitely feel more confident), Griffiths' book's starting to feel a bit "sloppy". My point is that, even though I do not know much of EM and I have little experience in solving EM boundary conditions problems, I know a little bit more of math: in my BS in chemE I've run into Navier-Stocks equations, conservation laws, and during last semester I ran into more advanced math like distributions, transforms, orthogonal expansions in Hilbert spaces, Green's functions ecc...

That's why I picked up Jackson. Next semester I'll attend a course in plasma physics and I know our professor will use Jackson's book a lot. I read a few random pages and I really enjoyed the insight he gives, but I also find some exercises very time consuming. I know exercises are very important, but I do not have the time to do 10/15 exercise per chapter as I did with Griffiths. I'd like to know if one can "go on" without doing a lot of exercises or not. One more thing: I suck at computing strange electric and magnetic fields, but I also hope to learn to do it during the course... I mean: to what extent do I have to know EM before takin the course?

All the topics are listed here (the evaluation is an oral exam at the end of the semester):

Really thanks in advanced for any suggestions.
