If you wish to get admission in MBBS in Karnataka or any other state then you will have to crack NEET as all the admissions will be done through that only (except AIIMS & JIPMER campuses).

Also, private and state counseling will be conducted by its particular state and for that you will have to apply seperately and for any state seats domicile would be a basic requirement so if you dont have Karnataka residential proof then you can apply there under 15% quota and for private colleges as you are not eligible for its 85% state seats.

Lastly, dont get confused crack NEET with required score then apply for 15% quota, state/private, deemed universities, AFMC separately.
