Hi aspirant,since you have 50.7 percentile in your JEE Mains most. probably so on this rank dear it is not possibke for you to get into the IPU or any college under IPU. For admission in IPU one needs to appear in IPU CET and clear it as well. So one can enter for IPU through JEE Mains and IPU CET only no other ways are there.

Good Luck.
