Hi David,
If it were me, I’d go through the lessons from the start, looking for something I didn’t realize I needed to know. Eventually you will start seeing things you want to concentrate on.
I re-listen to lessons from time to time while making lunch/dinner when I want a refresher. I think that works pretty well for a quick skimming when I can mostly listen, but no need to sit with the guitar.
