Apply again, as everyone else is saying.
I took my own tests over 30 years ago, but from much more recent experience (including a spell recruiting on the other side of the desk), I know the principles haven't changed much.
I was told my scores for Navigator were very high and better than for pilot, but I was quite shocked and said no thanks. Went back later and tried again. No luck, no change, so I set off on a different career path, outside of aviation. 12 months later the RAF wrote to me and offered me a commission as pilot, which I accepted.
I found out many years later that it is often just down to supply and demand and a little luck, right place, right time etc.
Good luck for yourself!
