i tried to to an arc flash certification, it took 6 hours for the course, at the end i failed the final test 2 times, so i called them to see what i can do, they said i have to do all course again, and pay again and again and again if i cintinue failing and is not cheap ,it is $136.45 canadian dollars. i understand that i need to pay attention, but this exams are extremely complex and diffucult questions, is kind of stupid, like if they want you to fail so you pay more. i will get another company to do this certification, i heard there are some canadian on line companies for 35 dollars
