This is the introduction to part 2 of this 4 course series. When I recorded this, I thought I would be doing a total of 3 parts. So please note that there are indeed a total of 4 courses in this Admin Certification series with a focus on Lightning Experience and just ignore that part where I mention a 3-part series.
Also since I recorded this, Salesforce has done away with the PDF exam guides in favor for an HTML version, which you will find via the link below.
