Ok then:
17 year young schoolboy, it seems that you have not gained enough information about becoming a pilot.
No worries, since you are in the wannabees forum so you questions are fair enough to me.
Working and getting a loan is not as easy as you put it.
I suggest you talk to your folks about that part.
Then, the pilot programmes. If you allready think that it is hard to get selected, you might want to disregard all the things about becoming an airline pilot.
It does not end after an integrated or modular course.
So I suggest you plow through the forums some more about all this.
