I honestly don't know about any online courses, that's a thing? I think you're probably better off asking questions on sites like these and getting a wide target area of expertise rather than the who-knows-how-reliable information from one singular person putting on a "course". Most of the people I've seen online doing up educational videos and whatnot usually don't know a damn thing and are just spreading bad/wrong information to the masses...I'm sure not all of them, but the ones I've seen have been pretty bloody useless and/or downright wrong.
