Life at FMS Delhi is not chilled out as it is one of the Top B-Schools in the country. FMS Delhi is a red building with some Classrooms and Academic Blocks while the IIMs have huge campuses. IIMs have hostel facilities for the Students while FMS Delhi students live in PG and Flats.
It depends on what Chill life means to you. Comparing life at FMS with IIMs in terms of "chilled out" can vary from individual to individual. Some students may thrive in high-pressure environments, while others may prefer a more relaxed atmosphere. Both FMS Delhi and Top IIMs offer excellent Education experiences.
