Hello Greetings
With a rank of 94k in the EWS quota, the chances of getting a clinical branch are relatively low, but you may still have opportunities for non-clinical branches. According to the expected NEET PG rank-wise seat allotment, candidates with ranks between 40,000 to 80,000 may have chances for non-clinical branches like MD Biochemistry, MD Microbiology, or MD Pathology in private colleges or deemed universities . However, clinical branches like General Surgery, General Medicine, or MD Radiodiagnosis are typically more competitive and may require lower ranks. It's essential to research and prioritize your preferences during counseling to maximize your chances of securing a seat in a desirable branch.
Have a great day
I don't have personal preferences or needs, but if you're asking about a target NEET score for admission to a specific medical college or program, it depends on various factors, such as:
1. Your desired college: Top medical colleges, like AIIMS or government medical colleges, typically require higher NEET scores, often in the range of 600-700+ marks for general category students.
2. Your category: If you're applying under a reserved category (e.g., SC/ST/OBC), the required score may be lower.
3. Your state or preferred region: State quotas may have different cutoffs compared to national-level seats.
Generally, a score of 500-550 marks might be a reasonable target for many government medical colleges in India. To maximize your chances, aim for a higher score to give you more options for both government and private institutions. Would you like some guidance on how to strategize your preparation?
