It is a bit difficult for me to really review this. We do the course every few years to continue to be in compliance. In reality we ship about 5 dangerous goods shipment a year and it is usually a very small amount of Lithium batteries, we receive about 40 or 50 a year, instruments containing lithium batteries - a ew coin cells usually. The course gives a good overview of the dangerous goods rules and responsibilities. If your company has very specific shipments I would suggest having someone address the specific rules associatted with those shipments. We did and now we just use this online course to keep our creditials up to date.
