As a newcomer to Dangerous Goods by Air I found this course extremely informative. Scott explained things in a very clear way which cut through the jargon which can often surround topics such as this. I particularly enjoyed the review quizzes and the fact that the modules could be visited multiple times, even after completion, to ensure all aspects of each module were understood. The course works as well with both electronic and paper versions of the DGR as students can work to their own pace. I would have no hesitation in recommending this course to colleagues who are either new to DG or as a refresher to those who currently hold a DG certificate
