Sorry for bad English
Do not be too hard on yourself, I suspect your English is better than most people's Arabic around these forums.
I would suggest you spend time reading the many learning experiences already posted in this section of PPRuNE.
In this industry it is very hard to say that anything is "for sure"; if you go to this or that school you will have this result. Let alone any guarantee some pay to fly scheme, some years in advance, will yield some sure outcome for you.
Sorry I am unable to give you the assurance you seek. But it was the same for most of us when we started studying for this career.
No guarantees except the promise of hard work.
I wish the best of outcomes for you.
Respectfully,
Northbeach
