If you would like an example to put some meat on the bones then I can tell you that I got a D and an E for my two A levels (Maths and PE) back in 1995 and I'm about to start my third fast jet flying tour so I wouldn't worry too much! They were followed by a Primary School Teaching Degree as well which doesn't exactly fit the normal Aero Eng' style degree!
The type of person you are is much more important than academic results.
Sorry for bragging about my A Level results. I know they could make alot of people jealous! They have been a source of much pride for many years now. Mind you they probably equate to 4 A*s in today's climate!
