I want to do marine engineering in tolani maritime institute of pune but my parents are not allowing me they are saying tht there is no life in marine engineering. and main thing tht the college is afilliated to bits pillani.

other option i have is only mechanical, entc, it , civil but tht is too common i want to do something different.

I know one college of pune IIAEIT but i m not sure about their placement.

so what should i do ?

and is thier any engg college which is also affiliated to bits pillani?
