Exam coverage

I will not ask questions about EM waves, on further reflection (<- you will see the pun after tomorrow's lecture. HA.) That leaves:

in the Knight book, Ch. 23.1-6, 24.1-7, 25.1-4. 

in the Serway book, 18.1-4, 19.3-9, 20.1-6, 21.1-3

or, by topic, dc circuits (multiple battery circuits especially), magnetic fields, induction, ac circuits (filters only, as in notes)
