Keep at it, I dipped 3 first time, re-took them with the second lot and got through. I dont consider myself to be bright, have kids and a full time job. Having said that I have worked bloody hard. You will meet some smart arses at groundschool who appear to be taking the lot in. Top and bottom is I still feel like I know sod all but have passed the same exams as they have with probably the same marks.
ATPL's are a weeding process which sorts those out who really want to do it. I too was one of those that looked at the coursework and thought I wasnt capable. Believe me we are all capable.
Getting a job will be the fun part!!!!!
Good Luck Matey
