I'm afraid I don't know the requirements over there.
I did, however, count at least 15 grammar and spelling mistakes in your post.
I would say that good spoken and written English is a prime requirement for an aviator in any army, so a bit more work here would not go amiss.
Remember that how you present yourself at the selection interview is probably more important than what science subjects you passed at school.
Good luck for the future.
