I second all of this. As for curriculum the basics are your friend!

Understand atoms and valence electrons 1st.

Get acquainted with ohms law and…

Tackle series circuits, then parallel then series parallel with resistive loads only 2nd.

If you’re feeling ambitious move on to ac theory capacitors and inductors, transformers and get comfortable converting polar to cartesian and vice versa.

Typically diodes and then transistors next.

Thats pretty much it for the low level.

Find a book that covers this stuff and avoid maxwell and the physics approach unless at some point you want to suffer / get really deep.

Also, flux. Lots of flux and alcohol to clean it up. Flux is the key to good solder joints, that and getting comfortable creating jigs. Whatever you're soldering has to remain still while the solder sets. Let the heat and capillary action do the work.
