      GATE Exam Pattern

      So, this was the updated GATE 2025 Syllabus. Now let’s check the 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 2025 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.

      GATE Cut-off Marks Mechanical

      It is also very important for the aspirant to know the previous cut-off. It helps us in better preparation in terms of time management, subject choices, and marks distribution. Here are the qualifying marks for GATE Mechanical Engineering.

      The GATE 2024 Cut-off is also released by IISc Bangalore. Check the GATE 2024 Cut-off below for Mechanical Engineering.


      GATE 2025 Organising Institute

      GATE 2025 will be conducted by IIT Roorkee in the month of February. The tentative dates of GATE 2025 are yet to be decided but it must be in the first and second week of February.
