Yes, that covers everything! I let my NREMT-P expire and all I had to do was take this refresher and retest both the skills and written and I was good to go. It takes time unless you can do every class as its scheduled. The classes are in 2 hour blocks and start at 1 and go through 24, if you can sit in front of a computer for a week, you can get it done fast but lets say they offer class 3 on Tuesday, they won't offer it again until they do all the other classes so it will be about a week before it comes around again. You can take the classes out of order though.
I hope this is helpful.
