Hello,


There is no entrance exam if you want to do Business Analytics course.You can do it online as well as offline.It is basically a Certificate course.
The duration of the course ranges from 6 months to 1 year.
Or you can do a full 2 years post graduate diploma in business analytics (PGDBA- which is jointly offered by IIT Kharagpur, IIM Calcutta and ISI Kolkata although the fees is very high for this course (20 lakhs) but pavement record is 100%.

ISB offers a 15 months parts time course in Business analytics.

Business Analytics & Intelligence provides by Indian Institute of Management (IIM B) in part time online and classroom program.

generally there is no entrance exam for admission into these courses.

I hope this helps.
