This post will be updated if any changes are announced by the GATE 2011 organizing institute. This GATE syllabus is a part of GATE 2011 Preparation: A complete Guide. I would also recommend you to refer A set of ‘Must Read’ articles for M.Tech aspirants which I wrote over a year answering questions of M.Tech aspirants.

Also you might be interested in Number of Students appeared in GATE 2010 and GATE 2010 Qualifying marks. Another good informative post is about Highest marks in GATE 2010.
