Securing an MBBS seat with 147 marks in NEET, even in the ST category, is highly unlikely.

The competition for MBBS seats is extremely intense, and cutoff marks, especially for government colleges, are significantly higher.

To improve your chances:

• Consider other medical courses: Explore options like BDS, AYUSH, or BSc Nursing.
• Prepare for NEET again: If you have the determination, dedicate another year to improving your NEET score.
• Explore private medical colleges: While expensive, private medical colleges might be an option.

Remember, the journey to becoming a doctor is challenging, but with perseverance and dedication, you can achieve your goals
