BARC 2018 ECE Exam Analysis

BARC ECE 2018 Day-1 Highlights

  • The BARC 2018 Day 1 Exam was in the morning session from 10 AM to 12 PM.
  • The paper level was little difficult or lengthy and more questions was 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 analog were little bit lengthy.
  • Around 4-5 previous year question were asked from GATE or ESE.
  • The Level of Questions from subjects Computer programming, Computer Organisation, Instrumentation and Analog were similar to GATE.
