Presidency University, Kolkata is a better to place to study economics than BITS, Goa, or Hyderabad. Presidency University, Kolkata is well known for its economics department. It also has an excellent subject record.
In the national ranking too Presidency University comes at the top. One of my cousins studies at Presidency University, Kolkata. And he vouches for the Economics degree provided by the institute.
Taking into consideration various factors like fees, faculty, it is safe to say Pracidency University is the better alternative.
But if you are looking for placement after graduation, then joining Presdancyi will not be a good idea. Although their Economics dept. Is well-renowned, they don’t offer placements after graduation. You will have better placement opportunities at BITS Goa.
