Hey there! Congrats on your NEET PG score - an AIR of 8883 is really impressive!

Regarding MS Orthopaedics seats, your chances at government colleges look pretty good with that rank. For RIMS Imphal and NEGRIMS Shillong specifically, it's a bit trickier to say for sure without checking their latest cut-offs.

Those are both excellent institutions, but keep in mind they tend to be quite competitive. Your best bet would be to check their websites or contact their admissions offices directly for the most up-to-date info on seat availability and cut-offs for MS Orthopaedics.

If you're open to other options, you might want to consider a few more government colleges to increase your chances. Places like AIIMS, PGIMER, and JIPMER are always worth a look.

Do you have any backup specialties in mind just in case? And are you set on those specific colleges, or would you be open to other locations?
