GATE 2017 ECE Analysis by Vishal Soni (AIR 25 in ESE 2015)

Hi Guys,

This post is for recently concluded GATE exam and in this post I wish to let you all know my verdict on GATE -2017 ECE paper. GATE-2017 paper for ECE was conducted on 4th Feb 2017 in two sessions i.e. Morning and Evening Session. A few general observations that I made about GATE-2017 exam are,

  • The paper was very balanced and questions were asked on diverse topics so that there was no dominant topic.
  • There were a few tricky questions which if not read carefully could lead to mistakes.
  • Questions were short so they did not require much use of the Virtual Calculator.

The weightage of different subjects in both sets were,


Subject Session-1 Session-2


Analog Electronics 9



Control Systems 9 11
3 Digital Electronics 11



Communication Systems 7 9


EMT 8 10
6 Maths 14



EDC 11 10
8 Network Analysis 5


9 Signals and Systems 11


10 Aptitude 15



Let me now comment on how was each subject in GATE-2017,

Analog Electronics

A very high weightage was given to Analog Electronics. The questions were spread across Diode Circuits, BJT Biasing and Op-Amp Applications and MOSFET. There were also certain controversial questions involving concepts of both BJT and Op-Amp so overall the level of questions from analog electronics was very good.


Control Systems

As always the weightage of Control Systems was considerable but it was heartening to see that all chapters found their representation in this year’s exam. So there were questions from Transfer Function, Time Response, Routh Criteria, Root Locus, Frequency Response, State Space Analysis and even Compensators. So no chapter could be considered irrelevant.


Digital Electronics

The weightage of Digital Electronics was same as previous years i.e. 10 marks. The questions were asked from different chapters in both sessions. In session-1 the more dominant topic was Sequential Logic Circuits whereas in Session-2 it was Combinational Logic Circuits.


Communication Systems

The weightage of Communication Systems was less as compared to previous years which is not justified considering the bulkiness of the subject. In session-1 there was no question based on Analog Communication but it found its way in Session-2. It was also surprising that not enough focus was laid on Random Process and Noise. Also, the questions were such that it required an in-depth understanding of concepts to crack the question.

This year the questions were asked on topics which are usually ignored like Information Theory. Also, there were a few questions which required application of more than one subject like there was a question based on Information Theory and Antenna.



The weightage given to EMT was as per previous years so no surprises there. There were a few questions in Set-2 which were based on basic Physics so solid understanding of basic concepts was required. There was no chapter which did not find its application in the paper. Also, there was a question based on Optical Fibre which is usually left untouched by GATE Aspirants. So we get to know that we cannot take any topic lightly.


Engineering Maths

As usual the weightage of Engineering Maths was somewhere between 12-15 marks. But this the most interesting aspect of Engineering Maths was that questions were based on in depth understanding and were not just calculative. Also, this year an increase in weightage of Vector Calculus could be clearly seen and such concepts are not very trivial. So, definitely the GATE Authorities raised the bar with Engineering Maths this time.



The surprising fact about EDC this year was that the weightage was quite high as compared to previous years. There were questions from almost every chapter but yet MOSFET was the clear favourite in Session-2 but in Session-1 more questions were based on Semiconductor Physics.

There was one or two questions which were not very trivial like there was one question based on Ambi-polar Transport Equation.


Network Analysis

Not to mention, Networks is most basic and one of the most important subject in Electrical Engineering but its weightage was pretty less as compared to previous years. The questions asked from Networks were mostly based on basics like solving networks or applying Network Theorems and one or two questions were also based on Sinusoidal Steady State Analysis.

Signals and Systems

This is one of the most important subjects in Electronics and Communication and its weightage is also quite high in GATE exam. This year the questions were a bit tricky and also mostly centred around LTI Systems.

General Aptitude

This section was pretty simple and Numerical Aptitude and Reasoning dominated Verbal Ability. Verbal counted for about 4 marks whereas Numerical Ability accounted for about 11 Marks.


GATE 2017 Vs GATE 2016?

One of the most asked question by GATE Aspirants is how was this year’s paper compared to last year is that how was this year’s paper compared to last year. So, I can point out a few differences,

  • This year’s exam was a bit more easy as compared to GATE 2016
  • The questions were such that there can easily be a mistake committed. So, a lot of students committed mistakes and ended up losing marks.
  • The questions were asked from topics that are usually neglected and ignored.
  • The questions in last year were more conceptual and required in-depth understanding of concepts.
  • Few questions were specially targeted to test the basics in different subjects.


Session-1 Vs Session-2

The overall toughness level was more in Session-1 as compared to Session-2. So, overall, session-1 students may get the benefit of normalization.


NAT Vs MCQ Type Questions

In Session-1 Technical Section, the weightage of MCQ type questions was 45 Marks and the weightage of NAT Questions was 40 Marks.

In Session-2 Technical Section, the weightage of MCQ type questions was 39 marks whereas the weightage of NAT Questions was very high i.e. 46 marks.

In Aptitude section all questions were MCQ Type.


Kreatryx Verdict

  • Most of the students lost marks this year due to exam temperament as they attempted the exam in a rush. This lead to ignorance of some points given in the question leading to incorrect answer.
  • The weightage of NAT Questions has been gradually building up over the years and the problem of accuracy in such questions is vital to GATE Results.
  • Many Students ignore Engineering Maths and General Aptitude throughout the year and focus only on Technical Subjects which led to their downfall in GATE 2017.
  • Cut-off shall remain almost same as previous year.
  • Average scores will be more than GATE 2016 but more than GATE 2017 and topper shall lie somewhere between 85-90 marks.


Kreatryx Recommendations for GATE 2018

  • Prepare all chapters equally well within a subject.
  • Do not ignore Engineering Maths and General Aptitude.
  • Focus on accuracy more than speed initially.
  • Create proper strategy and schedule for GATE 2018
  • Do not keep any presumptions about the exam.
  • Seek advice from only those who themselves have cracked the exam to avoid misguidance because “You may find many roads but only a few of them will lead to your destination”.
