Hello aspirant,
Based on the information available, securing an MBBS seat in A-category (Open) with 483 marks in Telangana might be challenging. However, there's always a chance, especially if the competition is relatively lower this year.
Here are some stepts that you can go through:

Check Previous Year Cutoffs: Analyze the previous year's cutoffs for BCB category in the Telangana OU region to get a better idea of your chances.

Explore Other Options: Consider other medical courses or colleges if securing an MBBS seat in A-category seems unlikely.

Counseling: Participate actively in the counseling process to maximize your chances of getting a seat.
The final decision will depend on the official cutoff released by the Telangana state counseling authority.
