@mckybob Welcome to BassBuzz!
When you have time, join us on the Introduce Yourself thread.
Learning the full songs isn’t intended to be done as you’re going through the course. @JoshFossgreen has said that as soon as you can do the easy workout to keep moving forward. There will be a disparity between the portion of a song he uses to reinforce the lesson and what is required for the complete song.
I hope that helps.
