With 340 marks in NEET and belonging to the OBC category, your rank will likely be between 200,000 to 250,000 nationwide. At this rank, getting a seat in a government or semi-government MBBS college is very unlikely in Andhra Pradesh or any other state.

Here's why: government and semi-government colleges usually fill their seats within the top 50,000 to 100,000 ranks. Even OBC reservations don’t typically extend beyond rank 120,000 to 150,000 for these colleges. With your expected rank, your best option is to look at private medical colleges, or consider deferred options for next year with better preparation.
