To everyone who has posted on this..........
Please see my comments in the Rules and Regulations Section.......
Here, I would say that the Advanced Certification Exam with its 50 multiple choice questions, 60 minute time limit and 80% pass mark is tough and very challenging.
No doubt.
I have written this test and I know others who have as well and we all agree there are at least 5 or 6 questions on this exam that have zero relation to the safe and responsible flying of your Phantom.
One question I got dealt with the name for some obscure meteorological event that even a highly experienced pilot wouldn't know.
I can say this because, after the exam, I asked a friend of mine with thousands of hours of corporate jet time and multiple trans Atlantic crossings this same question.
He had no clue.

And he agreed the question had no place on the exam.
These 5 or 6 obscure questions become important because in order to pass you need to get 40 of the 50 questions correct to achieve the 80% required.
These 5 or 6 questions can easily tip the balance against a successful outcome.
I certainly feel these Transport Canada Drone Pilot Certification Exams should be challenging;however, all the questions should be relevant and contribute to the safe and responsible operation of your Phantom.
At this point, it sure looks as though these obscure questions are on the exam to decrease the number of successful applicants.
