HELLO VAHID
Now since the official cutoffs for college are yet to be decided but let us analyse using previous year cutoffs
Since you did not mention the categories too let us assume it to bre general by default
B.Tech. in Computer Science and Engineering
3919(all india rank)
so as you can see your rank should be less than 3500 just to be on safer side.
Which means your percentile should be greater than 99.7+
well the marks equivalent to this percentile comes out to be 250+
HOPE IT HELPS!!
