Dear Aspirant,

Sorry for the late response.Though you have got 170 marks in your September attempt but are still facing some problems with the percentile you may contact the NTA helpline 0120 6895200.But there is no official process for rechecking.I cannot guarantee you that your percentile will change,but still you can give it a try.Hope your query is resolved.Best of luck.
