I took this course to fulfill my continuing education credits and I'm glad I did.  There is simply so much information to remember and this course covers ALL of it!  I cannot say enough about the professionalism, completeness, and methodology of quizzes (which explain the answers gotten wrong so that you can learn from them!).

Business ethics and practical contractor experience was helpful.  More info needed to prevent tampering with radon tests, with sample of non-tampering agreement to be signed by homeowner.

There was a technical glitch the first few chapters of the course, the video froze on occasion. 

I enjoyed the instructor, he included some of his mitigating experiences that are interesting.
