I am appearing for the GATE for life sciences in 2012. please tell me the reference books which can be read to get good knowledge about this exam. Please tell me from where I can download these books from the internet in PDF format. If I download the books in PDF, is it free to download.

As you Asking for the Syllabus of the Gate XL Life Science the Syllabus is given below
