I belong to Silchar and pursued my MBBS from NEIGRIHMS. This makes me qualified to talk about both. Here are some details on both these institutions-
NEIGRIHMS:
SMC:
If you are a domicile of Assam, it is better to do your MBBS from SMC. After your graduation, go for rural posting. After all this, you’ll become eligible for state PG quota. NEIGRIHMS has a very high competition for PG seats, and getting in for a UR student is especially difficult.
Both are equally good colleges, and you should choose between them based on your own preferences.
