I have never seen their courses not on “sale” so don’t let that trick you. I have taken some of their programming course though and they are excellent, so I would assume the finance ones are as well. Most of the courses are like $10 if I remember right so I would say its worth checking out.

If I was going to spend money on learning this stuff, it would be on the books on the [recommended list on the Bogleheads wiki](https://www.bogleheads.org/wiki/Books:_recommendations_and_reviews).

Udemy has all of their classes on sale through today, and a bunch of personal finance ones are on sale.  Does anyone have any experience with any that may be useful beyond what can be learned here?

Any Udemy classes worthwhile for investing knowledge?
