What subjects do I need to learn so I can have knowledge about Electronics and Electricity

Correct me if I am wrong. This is my guess about what I need to learn.

1st - Basic Electricity
2nd - Intermediate Electricity
3rd - Advance Electricity

So can you tell me what specific subjects or courses do I need to learn so I can have knowledge about Electronics and Electricity.

Well there are two main types of electricity: AC (alternating current) and DC (direct current)
You're going to want to start with DC first. Search for circuit analysis tutorials that cover things like Ohm's law, Kirchoff's laws, and parallel vs series circuits.
Eventually you'll move to AC which uses complex numbers (a real part and an imaginary part: 4+3i) to define all the same things as DC. There are some more complex things later on, but that should be a good start.
If you have questions you can message me at my blog below and I'll try to help you as much as I can

electronics is generally considered its own subject. there are various disciplines: high-power and/or high voltage, digital, RF, just to name a few. There are certain aspects of physics that will apply to all, and others that are only or particularly applicable to a given discipline.

those classes are probably to be an electrician to learn about electronics there isn't really such courses and are we talking high school or college here? because in college there are just courses designed for a major or trade...
