TSP - I'm sure that you'll find that the airlines couldn't give two hoots as to what grades you got in your ground exams. I think they'll take an interest in where you did you training and possibly if you got first time passes in the air. I believe that they are more interested in whether you will fit in with their company so that boils down to the personality tests and a good interview performance. At the end of the day it's all about selling yourself that you are the right/best one for the job, and that process starts with getting your CV noticed. If you did get high results in your ground exams then I suggest you include that in your CV eg "averaged 92% in ground exams". Best of luck for the future.
