Oh get off your high horse Ruthless. I don`t think anybody here is really advocating aiming for a minimum pass mark in groundschool exams
! Of course I`m sure you passed every single test you have ever taken with maximum marks
.
As Hufty said, its the person & personality that gets the job in the end. The only time an airline might see your groundschool marks is if you were put forward to a job through a training school and your training records were supplied.
Cheers.
