Hello all, Long story short, I am taking E&M course that uses Jackson, but in undergrad I only took 1 quarter of E&M (electrostatics). With classes about a month away, what would a good way to prepare. I realize that it is not enough time, but I figured some prep would be better that nothing. Would it be better to read/work through an undergrad text on E&M (griffiths or schwartz) or to spend the time going over math concepts (possibly vector calc and diff eqs). Thanks!
