The online dangerous goods by air course was very comprehensive, clear, innovative and professional. Being online the course saved a significant amount of time and money over attending a three day classroom course. The ability to repeat content as many times as required to achieve target scores and strong support from trainers when I had questions via the trainer hotline added to the quality of the overall learning package. Given the time saving, convenience and support I will definitely look to complete my refresher training in two years online.
