GATE 2023 Exam Pattern for Electrical Engineering

Type of Question

There will be two types of questions:

Multiple Choice Questions (MCQ)

Numerical Answer Type (NAT) Questions


There will be three sections in the question paper:

General aptitude

Engineering Mathematics

Electrical Engineering

General Aptitude SectionGeneral aptitude section will have 10 questions out of which 5 questions will be of 1 mark and the remaining 5 questions will be of 2 marks.
Number of Questions65 Questions
Marking Scheme

For 1 Mark MCQs - ⅓ mark will be deducted for every wrong answer.

For 2 Mark MCQs - ⅔ mark will be deducted for every wrong answer

For un attempted questions, zero marks will be given

There will be no negative marking for Numerical Answer Type (NAT) questions.
