BARC ECE Scientific Officer Exam Analysis 2021

BARC Scientific Officer Exam Analysis 2021 for Electronics and Communication (ECE) will be updated here after completion of the online exam. BARC Scientific Officer ECE exam is scheduled to be held from 5th to 12th September 2021. We will provide you with good attempts, the difficulty level of the paper, as well as topic-wise weightage that will help the candidates appearing in the subsequent shifts. As the written exam will be held in multiple shifts, therefore, normalization process will be used to calculate the score of the candidates. 

We will provide you with the detailed paper analysis for BARC scientific officer exam here. Meanwhile, you can check out the previous year exam analysis for your convenience here. This will help you to understand the questions that were asked earlier, topic wise questions with weightage.

BARC ECE Scientific Officer Previous Year Exam Analysis

Here you will find the previous year paper analysis for ECE exam. We have stated the number of questions that were asked in the exam as per the topic. 

BARC ECE 2018 Day-1 Exam Analysis

  • The BARC 2018 Day 1 Exam was in the morning session from 10 AM to 12 PM.
  • The paper level was a little difficult or lengthy and more questions were asked from instrumentation and microprocessors which was unexpected.
  • Not a single question was asked from Engineering Mathematics and Microwave Engineering.
  • The Questions from Network and control were easy.
  • EMFT, digital signal, and microprocessor questions were easy.
  • The Questions from EDC and analogue were a little bit lengthy.
  • Around 4-5 previous year questions were asked from GATE or ESE.
  • The Level of Questions from subjects Computer programming, Computer Organisation, Instrumentation, and Analog was similar to GATE.
