If you are getting a 65,000 rank in NEET and plan to join a veterinary college while preparing for NEET again, you'll likely be able to secure admission to a government veterinary college. If you get a better rank next year and choose to discontinue your veterinary studies to pursue MBBS, some colleges may impose a discontinuation penalty. However, the specific details of these penalties (amount, conditions, etc.) vary from college to college and may not be explicitly stated in the prospectus.
