Hello Aditya Rai!

I think a rank above 550+ in ipu bpt will be a good score so you can 

have the chances for top colleges in IPU for BPT. But it also depends 

that you are from outside or belong to Delhi.So try to bring a rank 

between 590-600+ if you are outside delhi .And if you of delhi i think 

rank of 500- 500 range will be good enough to get you a seat.

Hope this helps!!

Thanks!!
