Hello Gosu Dileep Reddy,

Congratulations on scoring 148 marks in JEE Main 2019. This year every shift had different outcomes of percentiles  for example :

One of my friend scored 152 marks on 11 Jan Shift 2 and her percentile is 95.52 while my other friend wrote JEE Mains exam on 9 Jan 2019  shift 1 and his percentile is 95.7 pr, so it depends on the level of particular paper you wrote on that particular day and Shift.

Moreover, your General category rank according to your score and considering year of passing 2019  is between 18,533 - 20,133 Rank.
