For the SC category, aiming for a percentile around 75-80 can put you in a good position for IIM Ranchi . However, it's essential to remember that cutoffs fluctuate yearly based on factors like the number of applicants, difficulty level of the exam, and available seats.

Domicile advantage might not be as significant for IIM Ranchi as it is for some other state-specific institutes. While it can be a small positive factor, your CAT score and performance in the subsequent selection rounds (like the Personal Interview) will primarily determine your admission chances.

Focus on thorough preparation for CAT and building a strong overall profile.

hope this helps you!!
