The question papers along with their respective answer keys are published below.
In GOAPS, a module to contest answer keys will be available from 00:00 hours of 27 February, 2016. Using it, a candidate can challenge the answer key of any question of the paper that he/she wrote. Hence do not send mails to us now about any disagreement that you may have with any answer key. For all disputes about answer keys, the decision of the GATE 2016 committee will be final.
The contest module at GOAPS will close at 23:59 hours on 2 March, 2016.
