I doubt your answer as the past year cut off was 8200 rank 

Hyy Rajnesh, 

Based on the basis of your CLAT Inputs and rank of 3794 with punjab resident, you have a very little or no chance of getting a RGNLU

now it completely depends on your luck, if seat is vacated then you'll get that college

If further doubts, do comment 

I hope this helps
