can i get nit with 88.52 percentile from general category.

Hello dear student,

The student as you belong from general category and also your expected rank would be 99673. So at this rank it will be really difficult for you to get admission into any NIT. While you can try  for the government colleges who give admissions in BTech or bi to the students on the basis of the jee mains marks

If you want to calculate your rank by your own then dear student you can do it as total percentile score is the percentage  of people ahead of you. 869010 are the number of candidates appeared for Jan exam. So rank formula is (100 - your total score) X 869010 /100.

Best wishes
