Sadly without the required grades, as 212man already said, you will have little chance if just applying. There are loads of people applying and looking at their educational qualifications is the easiest way to thin out the herd.They will miss out on some good pilots doing it this way but just like the military they have the luxury to pick and choose people that meet/exceed the require academic qualifications.Think twice before going for the Helicenter pilot selection day unless you can financially stomach it because it won't improve your chances to get over the first selection hurdle because it concentrates on the back end of the selection process.
