It may sound stupid but could I write CAT after passing out from the IPM program at IIM Indore?

Yes, you can take the CAT exam after graduating from IIM Indore's IPM program. In actuality, irrespective of where in India you graduate from, you are permitted to take the CAT as many times as you like. Even after they graduate from IIM Ahmedabad, some people continue to write the CAT for delight.

Now, it won't be simple to defend your decision in the interview stage if you want to take the CAT to enroll in one of IIM Ahmedabad, Bangalore, or Calcutta. If you're up for it, you can still give it a shot. One instance involves a woman who received her MBA from IIM Shillong before enrolling at IIM Ahmedabad. Another such incident where a guy completed his first year of the MBA program at FMS before leaving midway through to enroll at IIM Ahmedabad.

Consequently, it is true that individuals who have completed a similar program in the past have gone on to complete an MBA at the top IIMs. You simply need to put in more effort and convince the panelists effectively.
