**GATE** stands for Graduate Aptitude Test for Engineering is one of the toughest test, an all India Examination that basically test the comprehensive understanding of various undergraduate subjects in Engineering and Technology. It has been known for testing the engineering basics in a smart way. It need the effort of mastering an entire course of engineering (30+ subjects) which gives it a level of toughness in itself. It is jointly conducted by Indian Institute of Science and seven IIT’s on behalf of National Coordination Board-GATE, MHRD, Govt. of India, Department of Higher Education. GATE Score can be of help like it can be used to get into various Post-graduate programmes in Indian Higher Education Institutes that too with financial assistance provided by MHRD and other government agencies. It may be used by Public sector units for employment screening purposes.

**Electronics and Communication Engineering** course give great job opportunities in software and electronics companies. Software interface is required by all electronic devices to run and come with one or other device which controls programs architect and development is done by electronics and communication engineering. It provides great opportunities for research and development, as everyday consumer wants new devices to support them in daily life. Let’s go for the GATE Syllabus of Electronics and Communication Engineering 2014-
