Anyone with common sense can pass the ADR exam in 1 time, although some will have to put in more effort than others.
Learning the hazard classes
Especially learning the basics of ADR, the hazard classes, is a sometimes difficult threshold to overcome. After more than 25 years of experience teaching this subject, I know that the ability to learn the numbers and names of the hazard classes is a measure of whether a person can pass the ADR exam. Someone who takes too long to learn the classes falls behind that is often difficult to make up during the short duration of the course.
How do you prevent learning disabilities?
You can avoid falling behind in learning by learning the hazard classes before the course begins. In the course invitation, I give this as homework to my students. If students do not manage to learn the names and numbers of the Hazard Classes and Hazard Labels before the start of the course, I recommend postponing or canceling the course.
The red thread
During the first day of the course, extensive attention is paid to the different types of substances and the classes into which they are classified. Follow-up classes will cover class-related regulations. You will understand that much of the follow-up classes will pass you by if you do not master these basics. Indeed, the hazard classes are the common thread in the ADR course and recur in almost all topics.
Divide your energy
If during the course you have to put almost all your energy into learning this, admittedly important, but ultimately only relatively small part of the subject matter, you will miss a large part of the course and this will be reflected in the exam results.
Exam Results
Even though several hundred exam questions were covered during classes, during exams a mistake is often made (too) quickly. It is often evident from the results forms that, if you were to discount errors in hazard characteristics and preventive measures, almost everyone could pass.
Opinion:
So learn those classes ahead of time and you will almost certainly succeed.
