If you are looking for MBBS admission through the All India Quota (AIQ), the cutoff marks and ranks depend on the popularity and ranking of the college. For example, top colleges like AIIMS Delhi and MAMC Delhi have very high cutoff marks (above 690), while other government colleges in various states might accept ranks up to 15,000–20,000 under AIQ. If your NEET rank is below 3,000, you may get a seat in a good college through AIQ. As your rank increases, your chances may go down in central colleges but you can still try state counselling.
