With an All India Rank (AIR) of 8883 in the NEET PG exam and aiming for an MS in Orthopaedics, securing a seat at North Eastern Indira Gandhi Regional Institute of Health & Medical Sciences (NEIGRIHMS), Shillong, may be quite challenging. NEIGRIHMS is a prestigious institute, and the cut-off ranks for highly sought-after specialties like Orthopaedics are generally competitive.

For MS Orthopaedics, the cut-off ranks in government medical colleges typically fall well below 8883, often in the range of 3000-5000 for highly sought-after institutions. This can vary year by year based on factors like the number of seats available, the difficulty level of the exam, and the number of applicants.

To increase your chances:

1. **Check the Cut-off Trends**: Review the previous years' cut-off trends for NEIGRIHMS and other similar institutes.

2. **Participate in Counseling**: Engage actively in the counseling process. Sometimes, opportunities arise in later rounds or through spot admissions.

3. **Consider Alternatives**: Explore other colleges or specialties where the cut-off may align better with your rank.
