GATE Electrical Exam Pattern and Syllabus 2017

The Graduate Aptitude Test in Engineering (GATE) is an All-India examination administered and conducted in eight zones across the country by the GATE Committee comprising of Faculty members from IISc, Bangalore and other seven IIT’s on behalf of the National Coordinating Board, Department of Education, Ministry of Human Resources Development.

Exam Pattern

Questions will be of two different types :
(i) Multiple Choice Questions (MCQ)  
(ii) Numerical Answer Questions.
2. In all the papers, there will be a total of 65 questions carrying 100 marks, out of which 10 questions carrying a total of 15 marks are in General Aptitude (GA).
3. In the paper, the Engineering Mathematics will carry around 15% of the total marks, the General Aptitude section will carry 15% of the total marks and the remaining 70% percentage of the total marks is devoted to the subject of the paper.
4. The questions in a paper may be designed to test the following abilities : Recall, Comprehension, Application and Analysis & Synthesis.
