I'll give it to you straight and in your face.
Your problem:
You are not focussed. You want also others to spoon feed you with information. Part of the cohort of 100+ perfect scorers for A Levels? So what? So bloody what?! Singapore is so short of talent and anyone with such results, who has a decent heart, would have been snapped up by the GLCs. They are falling over themselves to offer scholarships to deserving candidates. The interviewers who rejected you did their job well - you have no heart to be RSAF material or on the receiving end of some scholarship. You may be brilliant but they have assessed your attitude and you don't deserve a scholarship, in spite of what YOU think. What is your hurry? You are stuck in NS until Oct 09.
Your solution:
Re-read the threads on cadets and self sponsored CPL holders. The answers are in there. If you can't be bothered to dig it out, tough ****. Oct 09 is enough time to read the threads THOROUGHLY. If you want so much to be an airline pilot, read the damn threads backwards and forwards until you find the answer.
