Amrita has good faculty and their experience will surely help students to reach higher levels

It is better than upes dehradun almost every student has been placed and the fees is also less here

All rankings of ASB have considered the coimbatore campus only.
However Amrita is a multi campus university with A grade by NAAC and the infrastructure and faculty are of impeccable standards at all campuses.

ITM Mumbai will be a better option amongst the two. XIME Kochi is new so it would be better to avoid it. ITM Mumbai has an average package of around 6lpa.

christ bangalore is the best

Avg salary is 6LPA and with 98% placements. Good college for all courses.
