Hi there,
Hope you are doing well.
With 38000 rank in CRL, your OBC Category rank would be around 10,000 which is very high to get admission in NIT Hamirpur.
According to JoSAA, for the year 2018, the closing rank for BArch in NIT Hamirpur was 532.
So, you don't have a chance to get a seat.
Hope it would help.
Thank You.
