Electric Charges, Fields, and Gauss's Law typically accounts for about 15%–25% of the AP Physics C: E&M multiple-choice section. That makes it worth dedicated practice even if your class spent only a few weeks on it.
Coulomb’s law, electric field computations, and application of Gauss’s Law to symmetric charge distributions. Expect questions involving Coulomb’s law and superposition for point charges; Electric field of continuous charge distributions (calculus-based); Electric flux and Gauss’s Law applications.
When you miss a question, tag it by skill (vocabulary, calculation, inference). Patterns in your misses show where to reread your notes.
