Anyone Tried Jerry Rosa’s Course?

New to mandolin. Looking for a structured course for beginners. I get lost in the sea of videos on YT. I am an average guitar strummer with a teaspoon of musical theory knowledge. Not a heaping teaspoon. I tried mando several years ago but got discouraged, with no direction, and quit. I’m back for more.

I can't speak to Jerry's course, but David Benedict has a series of beginner lessons on Youtube that take you from the very beginning and moves up step by step. Very good IMO.
