GATE 2017: Important points to remember
·         GATE 2017 examination will be conducted in 23 papers and candidate is allowed to choose ONLY ONE paper. Candidate should choose the paper carefully.
·         GATE 2017 score will be considered for 3 years for PG admissions and 1 or 2 years for PSUs recruitment process.
Virtual calculator:
·         GATE 2017 paper will have Numerical Answer Type (NAT) questions. There will not be any multiple choices for NAT questions. Candidate should enter the numerical answer through virtual key board after performing some calculations. Answer will be considered correct if it is in the accepted range.
·         For example: If the question is power delivered to some load in kW is ______. If candidate get answer as 5268 W, then answer will be any number between 5.2 to 5.3. Units are very important and more chances to do mistake in the calculations.
·         Another important point to be remembered is Physical calculator is not allowed in the exam hall. There will be online calculator and candidate should use it for calculations.
·         Conversion from polar to rectangular, complex numbers, Matrix operations, quadratic, cubic or simultaneous equations cannot be solved in this calculator.
·         It is highly recommended to use this calculator by downloading (from GATE website) into their mobiles/tabs/laptops during the preparation itself. Otherwise, it is great trouble during exam.
GATE 2017 question paper pattern:
·         In all the papers, there will be a total of 65 questions carrying 100 marks and duration is 3 hrs, out of which 10 questions carrying a total of 15 marks will be on General Aptitude (GA).
·         The questions will be of Multiple Choice and Numerical Answer Type questions.
·         General Aptitude: There will be 10 questions (both MCQ and NAT). 1 – 5 questions will carry one mark and 6 – 10 will carry two marks.
·         Engineering Discipline: There will be 55 questions (both MCQ and NAT) from respective specialized subjects. 1 – 25 questions will carry one mark and 26 – 55 questions will carry two marks.
·         Negative Marking: There will be 1/3rd negative for one mark MCQ and 2/3rd negative for two marks MCQ. No negative marks for NAT questions.
·         Design of Questions:
o   Recall: These are based on facts, principles, formulae or laws of the discipline of the paper. The candidate is expected to answer to able to obtain the answer either from his/her memory of the subject or at most a one line computation.
o   Comprehension: These questions will test the candidates understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.
o   Application: In these questions, the candidate is expected to apply his/her knowledge either through computation and logical reasoning. The questions may be a mix of single standalone statement/phrase/data type questions, combination of option codes type questions or match items type questions.
o   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 EE, EC and IN branches:
o   35% questions will be from common subjects. Ex: Digital electronics, Analog electronics, Network theory, microprocessors, control systems, signals and systems, transformation theory.
o   10 to 15% questions from mathematics, but they will not be pure mathematics questions and they mix with engineering applications.
o   35% questions will be from specialized subjects.
 Electrical Engineering: Power electronics, Electric Machines, Power Systems.
Electronics and Communication Engineering: Electromagnetic theory, communication engineering, electronic devices and circuits.
Instrumentation engineering:  Sensor and Industrial instrumentation, electronic measurements, optical instrumentation.
·         It is analyzed from the previous year’s papers that, paper setters are giving importance for fast growing/changing subjects and concepts related to those topics. For example, in EE paper applications of power electronics in power systems and in regulated power supplies used in house hold systems. In EC paper, digital communication, VLSI technologies are fast evolving. Hence, deep understanding with strong fundamentals is very much essential to score more in these subjects. Take expert’s guidance.
·         In every paper, there will be 10 – 15 subjects and number of questions is only 55 in engineering discipline.  Paper setting and equal weightage for all subjects is really challenging. Hence, IIT professors will make innovative and unique questions by combining two or three subjects. Such questions are very unique and candidate need in depth understanding and broader picture on the concepts.
·         Fourier series from Maths can be combined with Power electronics wave form analysis
·         Laplace transforms from Maths can be combined with network analysis, control systems, and signals and systems
·         Power electronics questions can be combined with electrical machines, power systems and maths
·         Matrices concepts like eigen value analysis can be combined with state space analysis in control systems and Inverse matrix calculations can be combined with power system load flow analysis.

I will suggest, while learning any subjects question yourself like below:

·         What is this concept? –This will make to understand the basic principle
·         Where it is used? – This will make to understand the real time application
·         How it is implemented? – This will make you to think in different direction and other alternatives.

Success Formulae:
·         Start your preparation from today itself and devote 6 – 8 quality hrs per day to understand the subject.
·         Revise the completed syllabus weekly, monthly once. Quality is important rather than quantity. Simple rule is, if you are not able solve any problem, it means your concept is not clear.
·         It is difficult to answer all the questions in the given time. So, you should focus on the questions where you score more.
·         During preparation also, make good time table and give importance for more scoring subjects and take suggestions from subject experts.
·         Business rule is until unless tested, a product should not released in the market. Same rule is applicable for student also. Without practicing tests (Online Test Series), you cannot perform well in the exam.
·         If you write more and more MOCK exams, you will get to know where you are weak and strong. So that you can get ready to exam more efficiently.
·         When you are preparing first time, make a neat notes and write down conclusions/formulae in separate notepad. It will be very useful to revise before exam.
·         Read standard text books referred by subject experts.
·         Solving previous papers of Civil Services, ESE and GATE will give an understanding on question patterns.
