Mam I have joined bsc(hons) zoology at hansraj college University of Delhi. How do I come to know which books I have to buy.

[@biologyatease]

Hey, first of all welcome to DU😊. I am also a graduate from DU( Zoology hons). Don't purchase any book, the best you can do is get your library books photocopied from Patel Chest( photocopy shops). For animal physiology , read tortora book and get is photocopied if possible. There is a photocopy shop near central library of North campus called - Alpha photostat, you will get all the suggested books from that shop, but i found those books with a little tough vocab so i used to issue books from my college library. So, either you go to alpha photostat and purchase the photocopied books from them or issue books from library. 😊 Have a beautiful DU life😜
