Hii sapna!

Unfortunately PGIMS rohtak does not publish any B.Sc. nursing past set papers and the university has shared only the structural details of exam like 180 mcqs across physics, chemistry and biology. But do not worry I am adding some sources from where you can get the PYqs :

1. Coaching websites publish practice sets
2. YouTube tutorials break down real CET questions, it will help you in understanding the question pattern and step by step logic.
3. Peer forums like career360, telegram channels may help you by sharing the scanned pdf or types version of PYQs, giving you access to real exam material.

Hope it helps!
