GATE 2016 is expected to take place on January 30 till February 7
next year. IISC, Bangalore conducts the exam to provide admission to
students in Master of Engineering degree programs. The score obtained in
GATE 2016 will be valid for a period of three years only from the date
of announcement of results.
From September 1, the online registration for GATE will commence and the last date for online filling of forms is October 1.
The syllabi for GATE 2016 papers have been revised and differs from those of GATE 2015.
Earlier there were total 22 papers, but now after the introduction of a new stream namely, Petroleum Engineering (PE) the total number of papers is 23. The duration of the examination will be 3 hours. There will be 65 questions and maximum marks will be 100.
The examination will be an online computer based test (CBT), which will contain multiple choice questions (MCQ).
One change that has been introduced this year is that now an online virtual calculator will be provided to all examinees during the examination, whereas earlier students used to get their own calculators.
The candidates can download their admit cards from the official website of GATE 2016.
