This is a good place to start if you aren't already overly familiar with the principle of electromagnetism and circuit theory: https://www.khanacademy.org/science/physics/electricity-and-magnetism https://www.khanacademy.org/science/physics/electricity-and-... After that the progression of a traditional EE education usually goes like this: transient and AC circuit analysis (phasors, Fourier, Laplace), linear systems, opamp and analog filter design, digital logic, some power stuff (3 phase, etc.), active devices (diodes, BJTs, FETs), RF basics. From there, the path usually splits based on your personal interest. Some options are usually power systems, digital systems (embedded systems), digital systems (IC design), AC design (usually mixed with RF).
