Project Orion is #1 courses on marketplace according to me.
At this price you get access to advanced and very cleary videos and also entry to community with others customers, everyone is very nice and helpful.
Trying to watch various tutorials on YouTube or udemy didn’t help me much, but by taking these courses my skills and knowledge increase and at this moment I am able to understand others and write my own code.
I definitely recommend it to all beginners or advanced
