But there is no option of b.pharm in ipucet

Ipucet is not the exam for bpharm.  Admissions are given based on your jee main score

You can go to http://www.ipu.ac.in and download the brochure. There is no mention of bpharm in it. I suppose you keep visiting the website regularly for updates regarding b pharm admissions. I read it here https://collegedunia.com/university/25450-guru-gobind-singh-indraprastha-university-ggsipu-new-delhi/admission that jee main paper will be used for admission to bpharm.

 Then how neet aspirant can register for b.pharm..???
