So, this was the updated GATE 2024 Syllabus. Now let’s check the GATE Exam Pattern.

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.

GATE 2023 EXAM PATTERN

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.

GATE Cutoff 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.
