In Andhra Pradesh, the 85% state quota is reserved for local/domicile candidates. Since you're from BC-E:

• Cutoffs for reserved categories (like BC-E) are usually lower than general and OBC-A/B/C.

• Based on previous years and expected trends, closing marks for BC sub-categories in government medical seats are often in the 200-300 range , sometimes even lower, far below your 460 .

Conclusion: With 460 marks, you are very likely to secure a free government MBBS seat under BC-E in the Andhra Pradesh state quota.
