UPSC conducts the IES 2020 Exam every year. IES, previously known as the ESE, was conducted on the 5th of January, 2020, this year. There are three stages of the exam- Preliminary Exam, the Mains Exam and the Interview Round. The UPSC ESE Prelims Exam was conducted on the 5th of January, 2020. UPSC IES Main is scheduled to be conducted on the 28th of October, 2020.

The UPSC IES Prelims results were announced on the 20th of February, 2020. Only the examinees clearing the Prelims cut-off shall be permitted to appear for the IES Main exam. The Electronics and Telecommunication Paper is divided into Paper I (General Studies and Engineering Aptitude) and Paper II (Electronics and Telecommunication Engineering). Pertaining to the guidelines, Paper II was a pen and paper based examination of a total of 300 marks with a time constraint of about 3 hours. This year, the UPSC mentioned a total of 495 vacancies.

ESE 2020 ECE Detailed Paper Analysis

The question paper overall, was not so lengthy, however, it did put to test the ability of the candidates to remain attentive while reading through the questions and options.

  • Electronic devices and circuits (EDC) - Last year there were 4 questions from EDC, but this year the number of questions has been reduced to 2. Both the questions were from photo devices, one was on the comparison of laser dynode and LED and the other was on the definition of quantum efficiency.
  • Material Science- Last year a handful of 13 questions were asked, however this year the number diminished by 3 and a moderate of 10 questions were asked. Out of these 10 questions, experts analyzed that 6 questions were easy could be solved with the help of examination prep and common sense; however, 4 questions were difficult as these were based on the mechanical properties of the materials an example would be the question that was asked on the critical distress part of the fracture of bitter materials.
  • Control System- The number of questions almost remain the same, last year it was 12 questions and this year 11 questions appeared on the paper. Unlike last year where there were numerical base questions, this year all the questions were from theory, mostly from the core concepts and the long questions were considerably easy. Overall, it was the scoring portion of the paper.
  • Electromagnetic Field Theory- As compared to last year’s 14 questions, this year there were 11 questions. The questions were consistent to last year’s and there was not much variation. 1 question each from static electric field and static magnetic field, 4 questions from antenna, and 2 questions from vector analysis. Out of the 11, the candidates could have easily scored a 10 from classroom notes and efficient examination prep.
  • Analog and Digital Communication- The number of 16 questions asked this year was more compared to last year’s 11 questions. 4 questions came from Analog Communication, 8 from Digital Communication. In the total of 16 questions, 8 were theory questions and the other 8 were numerical problems. The questions were evenly distributed and comparatively on the easier side. One can attempt a good 14 out of the 16 questions.
  • Basic Electrical Engineering- This subject was added recently in 2017 and has appeared in the last 4 years. Similar to last year’s paper, 8 questions came which were uniformly distributed. One question from the fundamentals, 2 from the transformer, 2 from direct current (DC) and 1 from induction. The questions were easier compared to last year’s.
  • Digital Circuits- Last year there were 10 questions and the number decreased to a 9 this year. Numerical questions were very few. Most were theoretical questions. The questions were well distributed pertaining to the syllabus. From sequences, there were 2 questions, from A to D converters there were 3 questions asked. The difficulty level of the questions was moderate.
  • Computer Organization and Architecture- This year 11 questions were asked, all theoretical. Among these- 5 were easy, 4 were moderate and 2 were difficult.
  • Measurement and Instrumentation- Weightage was similar to last year’s. 12 questions were asked as compared to last year’s 11. Questions covered the entire syllabus. They were on the easier side.
  • Advanced Communication- There were 11 questions this year- the number had reduced from last year’s 14. Out of these, 3 questions were from optical, 1question from satellite communication, 3questions from cellular communication and 1 from general data communication section. The questions were a lot easier compared to last year’s as all the questions were theoretical.
  • Network theory- A total of 20 questions were asked from this section. All were theoretical except one. There were no circuit questions. 8 questions came from the basics, 2 questions from graph theory and 1 question from theorems. The level of questions was very easy, experts pointed out that only 1 question was difficult.
  • Analog Electronics- There have been 12 questions from this section. All chapters were covered except Oscillators and Feedback. Out of 12 questions, 11 were easily answerable while one was a little difficult to solve.
  • Microprocessors - Only 4 questions were asked this year. They were very easy to solve and all were from within the syllabus.
  • Signal and Systems- 10 questions were asked, the number increased drastically compared to last year’s 4 questions. 2 questions were out of syllabus as experts analyzed that such questions were not expected in prelims.
  • Advanced Electronics- Last year there were 5 questions and this year also 5 questions were asked. Out of the 5, only 1 question was tough which was based on digital system design. The rest of the 4 can be easily solved.

ESE 2020 ECE expected cut-off

The cut-off is expected to increase. In 2019, the cut-off was 226. This year the expected cut-off is to be between 235 and 245. Overall, the experts did assert that the difficulty level of the paper was lesser, compared to last year’s.

In short, ECE graduates had a lot of scope to score their best provided their preparation was up to the mark. Now it is only a matter of time till you find out your results and in the meantime, start with your Mains preparation nevertheless. Best of Luck!
