Hi dear,

You have scored 86 percentile in JEE main that means your rank should be around 121661. However 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

Your sc rank will be around 4k-5k. With this rank you will definitely get NITs. You can predict your college here

Hope it helps.
