I've felt that Udemy courses are a good starting point for understanding a topic in a structured manner. Once you know the basics, you can move to a better, more expensive course.

For instance, I bought a course on mixing vocals in Ableton. I've watched dozens of YouTube videos on this topic and know enough, but none of my learning has been in a structured fashion. The Udemy course compiled all these lessons in a way that's better paced and structured.

Given that it was less than $10 compared to the hundreds of dollars higher-tier courses charge, I find it good enough value.
