It gives a day by day listing of what that day's lesson will involve once it's unlocked.
Granted, it only lists the General Path (as opposed to including the Chaosium path), but it should give you a good idea of what you will be learning, the milestones you should hit that would allow you to complete your first scenario within the 30 days.
I took the course a year or two ago, when it was C'thulhu only, and found it to be excellent, as Paul Fricker knows what the heck he is talking about when it comes to Call of C'thulhu and creating a quality scenario.
I didn't keep to the timeline, as things were hectic at best, but once you buy it, it's yours forever to go back to again and again to sharpen your scenario writing skills.
In my opinion, it's well worth the money.
