Both the colleges BIMTECH and Goa Institute of Management is decent colleges for management studies. Both the campuses are huge and offer good opportunities to students in upgrading themselves. NIRF 2021 ranked GIM 35 for PGDM/MBA. 

For a PGDM BDA, GIM will be a great choice. I have a few friends from the program and they had pretty great experiences pursuing the course.

• The course has a perfect balance of management and data analysis.
• It is powered by SAS, the world leader in analytics. It offers a variety of courses and a 5-month long summer internship. 
• The initial batch of PGDM BDA had a 100% summer placement average, due to which the batch size was increased to 120. 

If you are interested in doing a PGDM in BDA, GIM is definitely a great option.
