Hello Siva, You have got 53% in PCM, in plus two stage last year and you are now seeking admission to Marine Engineering branch. I feel you definitely can seek admission to this branch from the state from which you come from. The eligibility conditions for getting admission into engineering colleges which are government owned or government aided in the states is kept quiet low at about 50% in majority of the states and you have scored more than that. However in almost all the private Institutions the eligibility is kept at about 60% + and you will not be able to get admission, but it should not matter to you because you are still eligible to get admission in the colleges in your state. Best wishes to you.
