Dear student,

First of all, for BSC syllabus you will have to refer many various references book. Having just 1 is not helpful because some concepts are not covered fully in such books. I can give you few suggestions though how to access many books.

• College library

Your college library will have many such books, if your library has online mode try accessing those books ask your librarian for help they will be glad to help you.

• Ask teachers

Most of the teachers have such ebook at their disposal they could help you out.

Many book are not found online in pdf form due to copyright issues. So you might need to buy them.

Or another way is telegram. Download that app and joint those channels they give you access to various books and you can even ask the students there for any book you want. If they have you will get it for free.

Hope this helps you out.
