GATE Question Papers – Life Sciences (XL)


Here are the Gate Question Papers for Life Sciences (XL). I have uploaded the papers for last 3 years i.e. 2009, 2008 and 2007. Hope this will be helpful.

From GATE 2010 Biotechnology (BT), has been introduced as a separate GATE paper which was one of the optional section in XL paper.
