Hi dear,

You have scored 87.78 percentile in JEE main that means your rank should be around 106193. However this is not your final rank. Your final rank will depend on number of student appear in April month exam. You can also calculate your rank as

Rank =(100-your percentile)×869010÷100

You category rank will be around 25k-26k. With this rank you have low chance to get any NITs. You should reappear in april month exam and perform better.

Hope it helps
