The course does do a good job of helping you get the main concepts of how to build an MVC site down, setup templates and the manual routing solutions that come out of the box w/ Kentico. It really helped me quite a bit in my first site build and I've used it as a reference a few times. I would also recommend checking out a few blogs along the way that have helped me too!
The documentation is also very helpful and I find myself constantly going back and referring to it as I'm building a site.
The course is worth the money and as Brenden said, if you're a partner, you could get the course for a discount for free.
