Detailed ISRO Scientist/Engineer Electrical Exam Weightage Analysis

By Yash Bansal|Updated : December 31st, 2018

ISRO Scientist/Engineer 'SC' Exam 2019 for Electrical Engineering is out. The candidates who will be appearing the upcoming examination will get help from the detailed analysis for ISRO 2018 electrical engineering exam.

ISRO Scientist/Engineer 'SC' Exam 2018 for Electrical Engineering has been successfully conducted on 22nd April 2018 across the country. Total no.of vacancies for Electrical branch were only 6, so it is expected that a limited a no.of candidates must have appeared for the exam. Still, the exam level was maintained and a good no.of numerals appeared in the exam which tested the concepts of candidates.

Here we are providing a detailed analysis of ISRO EE Exam 2018 with weightage and an expected cutoff for the exam.

 ISRO Scientist Engineer Electrical Exam Analysis 2018

Here are some points about ISRO Scientist/Engineer EE Exam 2018

  • ISRO EE exam was one of the major exams in last previous years as most of the questions were numerical and required the basic knowledge of the subject.
  • No.of numerical were also increased and the level of numerical was Moderate.
  • Also, good no.of questions were given by General Physics
  • Maximum questions were from Network Theory, Electrical Machines, Power System.
  • Electromagnetics & Signal System weightage was reduced and the expected type of questions was avoided. 

Weightage Analysis of ISRO Electrical Engineering Exam 2018

Here we are providing the approx number of questions from each subject and marks weightage of that subject:

SubjectNo.of questionsImportant Topics
Network Theory13 (39 marks)Equivalent Resistance, Graph Theory, Time Constant of R-C Circuit, Steady State & Transient Analysis, ABCD parameter Calculation, Thevenin's Theorem, KVL & KCL Application, Tank Circuit, Dependent Source Circuit, A.C Circuits.

Important Points for ISRO Scientist/Engineer Exam 2019

  • We could expect ISRO 2019 examination accordingly and would prepare as per previous analysis.
  • As per the analysis of ISRO EE Exam, the expected cut off will be above 150-180 Marks. The exam was quite Moderate and candidates had already prepared for ESE, GATE, and BARC exams, so it seemed easy to most of the aspirants.
  • No.of questions from Engineering maths is around 7-9, which was a bonus for all aspirants.

Note: ISRO will be providing official answer keys in coming days, so candidates should wait for it and should not get dishearten if answers do not match according to any institutes respective answer key.
