Alok, world is a strange place and we get to hear lot of things, But what we take to our heart depends on us. Now CMAT score is not considered for JBIMS.  MAH CET is a State level entrance exam. In fact, truth be told, JBIMS considers CAT/MAHCET. GMAT is for Foreign Nationals. So, CMAT isn't even in the picture. So if you want to take admission in JBIMS, you should appear for CAT or MAHCET. Now CAT exam has already happened and it is not clear whether you have appeared for CAT or not. So you should appear for MAHCET for admission to JBIMS because your MAHCET score carries 60% weightage for being shortlisted for JBIMS.
