Hi there
For getting Merit seat in MBBS or BDS you have to write NEET exam.
Around 14 lahk candidates appear for this exam annually and around 7 lakh get admitted in various parts of India.
Last year the cutoff marks range was 701-134..
Minimum 50% are required for general category for NEET eligibility and 45% for SC/ST.
Hope this will help you.
Thank you
