What is the best source of EM problems relevant to the GRE is your opinion?
I'm assuming based on the syllabus that a text like Griffiths is appropriate.
Would it be adviseable to attempt most of the problems in Griffiths? How about Haliday and Resnick?
2. ELECTROMAGNETISM: 18%
(such as electrostatics, currents and DC circuits, magnetic fields in free space, Lorentz force, induction, Maxwell's equations and their applications, electromagnetic waves, AC circuits, magnetic and electric fields in matter)
3. OPTICS AND WAVE PHENOMENA: 9%
(such as wave properties, superposition, interference, diffraction, geometrical optics, polarization, Doppler effect)
