Strategy to score 65+ in GATE(ECE)

What is GATE ?

Gate stands for Graduate Aptitude Test in Engineering.Graduate Aptitude Test in Engineering (GATE) is an acronym for Graduate Aptitude Test in Engineering. It is an annual entrance exam for entry to various postgraduate science and technology systems in Schools. The exam is jointly administered and supervised by the Indian Institute of Science and seven Indian Institutes of Technology (IITs) on behalf of the Ministry of Human Resource Development’s Department of Higher Education.

The GATE Score is also very useful in finding the prestigious jobs with attractive salary packages in many Public Secor Undertakings(PSUs) recruitments. The PSUs who uses GATE score for providing jobs includes BHELBARCIOCLNTPCHPCLPower GridNHPC, etc.

Analysis and Weightage of GATE (ECE) :

From above analysis we can conclude the subjects that carry much weightage but we have to thoughtfully concentrate on the weightage area as communication carries more weightage than any of the subjects but its syllabus is very vast and hard though . So we have to wisely choose the topics to start our gate preparation.
