GATE Exam Pattern

If you are preparing for GATE Paper, it is important to know the syllabus but it would be very good if you also know the pattern of the exam. This helps us effective preparation for the preparation.


The exam is conducted online every year in the month of February. The GATE 2023 exam pattern was as follows-

  • Total Number of Questions- 65
  • Total Marks- 100
  • The Exam Duration- 3 hours.
  • The paper consisted of two types of Questions- Objective Type Questions (MCQs) and Numerical Answer Type (NAT) Questions.
  • Negative Marks for Objective Type Questions (Multiple Choice)
  • But No Negative Marks for Numerical Answer Type Questions.
  • There were three Sections- General Aptitude, Engineering Mathematics, and Engineering Specific Subjects.

Marking Pattern

The General Aptitude Paper consisted of 15 questions

  • Total Marks- 15
  • 5 Questions consisted of 1 mark
  • Another 5 Questions consisted of 2 marks.

Negative Markings

  • For 1 mark Multiple Choice 1/3 mark deduction
  • For 2-mark Multiple Choice 2/3 mark deduction
  • No Negative Marks for questions not attempted
  • No Negative Marks for NAT Questions

Note- In the NAT-type questions, the students with the help of a mouse and virtual keyboard have to type their answers in the blank space provided. The answer could be any real number.
