Hello,
If you have 60% aggregate marks in pcm in class 12th board exams  ( all taken together ) then only you are eligible for admission in Tolani Maritime Institute.
But it don't looks like you have 60% aggregate marks in class 12th board exams so you are not eligible to apply for that.
Good luck.
