Graduate Aptitude Test in Engineering (GATE) is an examination that primarily tests the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/Architecture and postgraduate level subjects in Science. The GATE score of a candidate reflects a relative performance level in a particular subject in the examination across several years. The score is used for admissions to postgraduate programs (e.g., M.E./M.Tech/ Direct Ph.D.) in centrally funded Indian Institutes of higher education (i.e., Institutes which are provided with financial assistance by MHRD and other Government agencies). The score is also used by some Public and Private Sector Undertakings for employment processes in India. Direct recruitment to
Group ‘A’ level posts i.e., Senior Field Officer (SFO Tele), Senior Research Officer (SRO) (Crypto) and SRO (S&T) in Cabinet Secretariat is now being done on the basis of GATE scores.
This year GATE 2017 examination shall be held in Bangladesh, Ethiopia, Nepal, Singapore, Sri Lanka and United Arab Emirates for admissions of candidates from these nationalities in IITs and IISc.
The information in this brochure is mainly categorized into PreExamination (Eligibility, Application submission, Examination Centers etc.), Examination (Syllabus, Pattern, Marks/Score, Model Question Papers etc.) & PostExamination (Answers, Results, Scorecard etc.) sections.
The Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) jointly administer the conduct of GATE. The operations related to GATE in each of the 8 zones are managed by a zonal GATE Office at the IITs or IISc. The Organizing Institute (OI) is responsible for the endtoend process and coordination amongst the administering Institutes. Indian Institute of Technology Roorkee is
the Organzing Institute for GATE 2017.
1. Examinations for all the 23 papers (disciplines) will be conducted by an ONLINE Computer Based Test (CBT). A candidate can appear only in any one paper of the GATE examination. The online examination paper will contain some questions for which numerical answers must be keyed in by the candidate using the virtual keypad. Rest of the questions shall be of Multiple Choice Question (MCQ) type. A virtual on screen calculator only shall be used during examination.
There shall be use of virtual calculator ONLY to be provided by GATE. Physical calculator, mobile phone and wrist watches with calculation facility are strictly prohibited and candidates possessing these in the examination hall (even if not using) shall be disqualified.

In the papers bearing the codes AR, CY, EY, GG, MA, PH and XL, the General Aptitude section will carry 15% of the total marks and the remaining 85% of the total marks is devoted to the subject of the paper.
GATE 2017 would contain questions of two different types in various papers:
(i) Multiple Choice Questions (MCQ) carrying 1 or 2 marks each in all papers and sections. These questions are objective in nature, and each will have a choice of four answers, out of which the candidate has to mark the correct answer(s).
(ii) Numerical Answer Questions of 1 or 2 marks each in all papers and sections. For these questions the answer is a real number, to be entered by the candidate using the virtual keypad. No choices will be shown for this type of questions.
Design of Questions
The questions in a paper may be designed to test the following abilities:
(i) Recall: These are based on facts, principles, formulae or laws of the discipline of the paper. The candidate is expected to be able to obtain the answer either from his/her memory of the subject or at most from a oneline computation.
Example
Q. During machining, maximum heat is produced
(A) in flank face
(B) in rake face
(C) in shear zone
(D) due to friction between chip and tool
(ii) Comprehension: These questions will test the candidate’s understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.
Example
Q. A DC motor requires a starter in order to
(A) develop a starting torque
(B) compensate for auxiliary field ampere turns
(C) limit armature current at starting
(D) provide regenerative braking
(iii) Application: In these questions, the candidate is expected to apply his/her knowledge either through computation or by logical reasoning.
Example
Q. The sequent depth ratio of a hydraulic jump in a rectangular channel is 16.48. The Froude number at the beginning of the jump is:
(A) 5.0 (B) 8.0 (C) 10.0 (D) 12.0
The questions based on the above logics may be a mix of single standalone statement/phrase/data type questions, combination of option codes type questions or match items type questions.
(iv) Analysis and Synthesis: In these questions, the candidate is presented with data, diagrams, images etc. that require analysis before a question can be answered. A Synthesis question might require the candidate to compare two or more pieces of information.
Questions in this category could, for example, involve candidates in recognizing unstated assumptions, or separating useful information from irrelevant information.
For 1mark multiplechoice questions, 1/3 mark will be deducted for a wrong answer. Likewise, for 2mark multiplechoice questions, 2/3 mark will be deducted for a wrong answer. There is NO negative marking for
numerical answer type questions .
A few performance and statistical data from GATE 2016 examinations are provided here for the candidates to make a self assessment of the examination.
