Dear Somay,

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!!
