Hi Manasa,

PV Publishers have a copyright on their books, nobody can copy that, so you have the only option to buy the books from the publisher only. So, buy  b pharmacy 3rd semester books from their official site only. Search " PV Publishers b pharmacy 3rd semester books" and then go to the first website that appear and buy the books.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!
