Can a general category student convert IIM Indore or Shillong at 92 percentile? (With a reasonably okay WAT-PI) (with good academics but as a fresher)

Yes, considering your profile, you can convert IIM Indore and Shillong at 92 percentile. Your excellent academic record will compensate for your CAT score and increase your chances of getting selected.

Since you are a fresher I will suggest you analyze your career aspirations before choosing a college. What made you choose IIM only. Is it just because you want to get placed and earn a high salary? I suggest you try broadening your career options by identifying your area of interest. Some career options with their suitable colleges are

• If you want to go for Mass Media, you can join Jamia or Prahlad School in Mumbai.
