Greetings, 

Abhishek ,you cannot take admission into INDIAN MARITIME UNIVERSITY because for that you need to give IMU CET which requires that the candidate should have  :  

1. 60% aggregate marks in 12th in subjects -Physics, Chemistry and Mathematics 

2. You need at least 50% in English 

As you took commerce in your 12th standard you are not eligible to give this entrance exam and without which you cannot get into any of IMU's . Even private colleges ask for the candidate to should have his/her subject as physics, chemistry and mathematics .

There are some colleges for which take admission on the basis of your JEE entrance exam score but even for that you need science as your subject . There are various state board entrance exam also like AP EAMCET , WBJEE , GUJCET , MANET-CET but even to fulfil the eligibility criteria of these entrance exam , you need Physics, Chemistry and Mathematics as your subjects in 12th standard .   

I hope this article might have helped you provide an answer . Even after that if you are not satisfied do drop a comment or post another question and I will sureluy help you out
