My average score was 87% and during an airline interview I was asked why it was so low and in which subjects my performance was weakest. In the end it did lead to me being offered a job, but I would rather preferred not to have to explain myself about it. It's not among the main things they are looking at but if you can, nailing the exams is the best way to go. In this harsh industry if they find anything about you they dislike, they have all the right to throw your CV into the bin
