**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.
