Dear Aspirant, if you belong to general category 50% is the minimum percentage of marks required to qualify for NEET in class 12th Board Examination but you have got 49% but if you have any quota then you are qualify in that criteria. But 163 marks in NEET is much less to to get BAMS as per previous years trends. I hope you are clear now. If you have any other doubts feel free to ask. All The Best!!!
