Hello aspirant!
Answering your question-
Other state students cannot apply directly for MBBS/BDS seats in Tamil Nadu.they have to come through all India quota by applying in Neet examination only.
To be considered for admission to state quota seats, the candidate has to be a native of Tamil Nadu and should atleast study 5 years that is from class 8th to 12th in Tamil Nadu are considered native of Tamil Nadu and can apply directly.
Others have to get a nativity certificate to apply that is the parents of candidates should atleast live in Tamil Nadu for atleast 5 years to get a nativity certificate.
Hope this helps you.

Hi Prakash,

For your information, the eligibility for admission to any Medical College of Dental College giving an MBBS or BDS degree across the nation except for some like AIIMS , Jipmer and CMC Vellore, the Neet examination is the common entrance for all of them.

After you get your marks and rank, you need to definitely get in excess of 360 out of 720 to be held eligible for counselling for even the private medical colleges.

For government medical colleges you might need to score more than 600 if you are applying by the 15% all India quota or usko in excess of 500 to 550 for the 85% state quota seat availability
Since you are aiming for a private medical college the marks barrier for you might be somewhere in between 380 to 420.

Hope this helps!!! Thank you
