Hi Dear,

IPMAT is a national level test which is a gateway for admission to the five- year Integrated Program in Management offered at IIM Indore. IPMAT open your doors only for IIM Indore. whereas CAT test is a national level exam for admission in postgraduate management program in 20IIMs and many other top B schools of India. CAT has a wider scope when compared to IPMAT. I'll suggest you to go for CAT. However, if you do not wish to write exam again and wish to pursue BBA course in your graduation, then IPMAT is also a decent option.

Good Luck
