Hey G-MIDY
Those results sound fine to me! As the others have said, what counts more than anything is the GCSE and A-level results.
This especially applies if you are looking for a sponsorship deal with an airline (few and far between these days) as they want to get a feel for your academic qualities before injecting X amounts of money into your training.
If you look at the other extreme. All you need to hold a PPL is to be able to pass a medical, pass the written exams, and above all be able to demonstrate your ability to aviate safely when it comes to your flight test.
One of the other guys on here said keep focused, and determined. Too right!!
If I'm honest it's quite tough at times to do the commercial training but if your heart's in it you'll achieve your aim. It's taken me nearly 3 years but now I'm very happy working as an instructor. (Still flying the little aeroplanes that we take you up in on trial flights) Just proves what Wireless said!
Keep with it mate!
Happy landings
