I can't help with Singapore I'm afraid as I have no experience with them, but I thought the following might cheer you up.
When I joined BA 30 years ago there was a shy young man on my course who had tried 19 times to get into BA, and failed. He was distraught, and decided to give it a 20th go. Voila! Success....he is now a very well respected CSD, and has had a fabulous career. I am proud to call him a friend.
Never give up!
wow what a wonderful inspirational story, just shows no one shall ever give up their dreams :-)
