Two public lessons are open. Later units stay on this map as unpublished. Completing a listed card after the gate is not a complete E&M course. Coverage is objective evidence, not videos watched.
Bridge: Prerequisite repair
Vectors, graphs, derivatives, integrals, separable DEs, and mechanics ideas that E&M will use. Weak calculus opens these alongside physics, not instead of it. MCQ weighting not examined as a unit.
Unit 8: Electric charges, fields, and Gauss’s law
Charge as a conserved source; the field as a vector model; superposition and integration; flux and symmetry-based Gauss’s law. MCQ weighting 15–25%.
Unit 9: Electric potential
Potential energy of charge systems, potential difference, and the field–potential relationship, including reference choice. MCQ weighting 10–20%.
Unit 10: Conductors and capacitors
Equilibrium in conductors, capacitance from geometry, stored energy, and dielectrics with the battery connected or not. MCQ weighting 10–15%.
Unit 11: Electric circuits
Current, resistance, energy transfer, networks with Kirchhoff’s rules, and RC transients. MCQ weighting 15–25%.
Unit 12: Magnetic fields and electromagnetism
Magnetic force on charges and currents; fields from currents via Biot–Savart and Ampère’s law. MCQ weighting 10–20%.
Unit 13: Electromagnetic induction
Changing flux, induced emf and current, inductance, RL transients, and LC energy exchange. MCQ weighting 10–20%.
