The test I had to do a couple times only because I didn't realize that there was more than one answer for some of the questions. I am a NCSO for the company I work for, and I did feel.like that was probably the hardest test out of any courses I ha e ever taken to aquire my NCSO status. But that being said I did find the course very knowlegable. I have taken a asbestos awareness course before through Golder associates and that was in class and I still found this online course better. All in all test needs to be simplified a little bit my guys that took the course were having alot of difficulties with the test as well
