MBBS

Yes, you can use this score to study MBBS in India.

Firstly, give IELTS exam, then search for colleges that may give you admission considering you class 12th scores and IELTS bands.

Yes, you can do PG from any country, remember to meet all the eligibility criteria of the college you want to apply for admission.

You can pursue an M.Sc in Forensic Psychology - 2 Years (4 Semesters) Duration Full Time Course in Gujarat Forensic Sciences University. You are already a Physician so no need for a Psychiatry. LLB should be pursued in Law Professional College - Fulltime only with Entrance Exams. LLM can be pursued after BL/ LLM.

For this college, you have at least 10k rank in NEET.

According to your marks, it is nearly impossible to get a seat through All India Counselling in NEET and also, quite tough to get through state counselling but yes, there is a chance. I will suggest you to participate in state counselling for MBBS seats or you can try in private colleges if you want better facility compared to state government medical colleges.

You have not mentioned these marks are in which exam, out of how much max etc. Please try to give full information and then ask query. For MBBS one needs to clear NEET exam. Best wishes to you.

No, there is no entrance exam the admission is through state level counseling about 85%and remaining through NEET.
Well for more clarification u can once go through from this link.
All the best.
