Suppose an advanced undergraduate student has reached a moderate level of understanding on electrodynamics. Where should he focus on, to sharpen his problem-solving skills?
- Practicing integrals and/or other mathematical tools.
- Studying theoretical results.
- Working on the physical meaning and applications of ED equations.
- Something else.
I understand this is a somewhat subjective question but please try to be as objective as possible: state what really works based on your experience as a teacher/TA for example
