Yes. IIMB does require the CAT exam, but the rest of the top B-schools in Bangalore also take in candidates through the state-level CET, ie, the Karnataka PGCET exam, or through MAT or CMAT. 

Note: All info. is from official sites and can change.  

IIM Calcutta has only mentioned accepting GMAT score for admission into EMBA courses.

However, CAT is commonly accepted by other similar institutes for both MBA and MBAEx courses. Thus, candidates are advised to ask admission desk for confirmation on this question.
