IIM Calcutta - Indian Institute of Management Joka Kolkata Answered Questions

IIM Bangalore gives more weightage to past academic performances + work experience and less weightage to CAT marks whereas IIM A&C gives high weightage to CAT marks only. So, you've got high chances with IIM A&C if you score well in CAT and medium chances with IIM Bangalore.
IIM Bangalore Final selection (66 Marks) = CAT (20) + X (15) + XII (10) + UG (15) + Work Experience (6). So, 30% of the weightage given to CAT and 70% weightage given to academics + work experience.
