My own view of these online courses is this - why?
They cost a fortune and I'm not so sure you will learn anything you can't learn for free, or very little. A friend of mine recently started some such course, despite me suggesting he shouldn't. Well, he's up to module 7 out of 10, and despite being way past halfway, as far as I can tell he hasn't actually learnt
anything new about actual photography. Instead, he's now an expert on dynamic range, histograms and such, all important aspects as you will agree but none of this has taught him how to take a good photograph, by his own admission his photography still "sucks". The cost of this course was something like £300-£400

Everything he has "learnt" could have been picked up from reading one book. He still doesn't shoot in manual because he doesn't fully understand how to. Not that shooting manual makes you a good photographer, I'm just saying surely he should know how to by now, after 7 modules in a 10 module course :shrug:
He doesn't know how to meter, he hasn't been taught how to. He doesn't know anything about how to compose at all, it hasn't been covered, and anyway how would you teach good composition with a short written module followed by one exercise (which is how the course is structured)?
This course is one of the big online courses, it isn't one of the dodgy ones. When you're finished you get a "qualification"
I would suggest, you read as much as you can, there are plenty of online sources, how to's and this excellent forum too. You also learn best by
doing so shoot shoot and shoot some more - it doesn't cost anything. Attend one of the meets in your area, if there isn't one then organise one, like I am doing for my area. Ask questions on here too - you will always get a good answer or twenty. Pick a magazine you like, follow the tutorials.
Save yourself a lot of money and spend it on better/more equipment instead
Happy learning
