Hello Roshan,
Placement cell of Manipal is quite good. But, if the Industry is not doing well then placement will not happen. Aeronautical Engineering is unfortunately in this category. Alumni response is quite discouraging. But then where are the companies doing research in aeronautics in India? You may get job in a production line. Majority of the students go abroad for PG.

DU is the best option to pursue English (Hons). You can learn music too.
Good luck.

IIMC is the best college for mass communication to pursue Masters.
