GATE 2017 coachingGATE

GATE-2017 Introduction

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 post-graduate 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 post-graduate 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 Pre-Examination (Eligibility, Application submission, Examination Centers etc.), Examination (Syllabus, Pattern, Marks/Score, Model Question Papers etc.) & Post-Examination (Answers, Results, Scorecard etc.) sections.

About GATE-2017

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 end-to-end process and coordination amongst the administering Institutes. Indian Institute of Technology Roorkee is

the Organzing Institute for GATE 2017.

Basic Features of 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.

2. Biometric information (Photograph and Fingerprints) for randomly selected candidates may be captured before the start of the examination.

3. GATE 2017 examinations will be held during forenoon and afternoon

sessions on weekends (Saturday and Sunday) on 4th, 5th, 11th and 12th February 2017. Examination for some of the papers in GATE 2017 will be held in multiple sessions. Exact details regarding complete examination schedule will be notified at a later date, on the GATE 2017 website. The candidate has to appear at the GATE Examination Center on the date and time specified in the admit card; no request for any change in Center or Date/Time shall be entertained. Similarly, this being an examination body with certain constraints, candidates needing very special or specific facility for the exam may not be entertained. Hence, candidates are requested to adhere to the facilities that are possible within the ambit and resources of GATE exam body.

The session timings at GATE International Centers as per their local time shall be notified well in advance.

4. For GATE 2017 the entire process of filling up of application form, uploading of certificates/documents etc., shall be online only and the candidates should not send any hard copy of his/her application form/documents etc., to IITR or any of the IIT’s zonal GATE office.

5. The payment of application fees would be through electronic mode; online as well as through payment at bank counters using e-challan.

6. The admit cards for GATE 2017 would be available through the online process only. Candidates can download their admit card from GATE 2017 website. Candidates need to download and print admit cards from gate website and NO printed copy of admit cards shall be sent by post to the candidates.

Pattern of Question Papers

In all the papers, there will be a total of 65 questions carrying 100 marks, out of which 10 questions carrying a total of 15 marks will be on General Aptitude (GA).

In the papers bearing the codes AE, AG, BT, CE, CH, CS, EC, EE, IN, ME, MN, MT, PE, PI, TF and XE, the Engineering Mathematics will carry around15% of the total marks, the General Aptitude section will carry 15% of the total marks and the remaining 70% of the total marks is devoted to the subject of the paper.

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 one-line computation.


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.


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.


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.

Marking Scheme

For 1-mark multiple-choice questions, 1/3 mark will be deducted for a wrong answer. Likewise, for 2-mark multiple-choice questions, 2/3 mark will be deducted for a wrong answer. There is NO negative marking for

numerical answer type questions .
