Info about Joining Merchant Navy

Respected Sir,
I have recently appeared for my 12th Science HSC exams. I am awaiting my results that will be out by First week of June.

I am willing to JOIN the Merchant Fleet as a Cadet.
I do know that I should have above 60% in 12th.

I have certain Doubted Questions.....Would be great If you Answered ALL of these... :-)

Q1) I wanted to know which colleges would be best...
