GATE Syllabus For Mechanical Engineering 2023

GATE exam is a computer-based test conducted by the Indian Institute of Science (IISc) Bangalore and the seven Indian Institutes of Technology (IITs) at Bombay, Delhi, Kanpur, Guwahati, Kharagpur, Roorkee, and Madras. This exam is conducted on behalf of the National Coordination Board (NCB)-GATE, Ministry of Education (MoE), Department of Higher Education of India.

Who will organize the GATE 2023 Exam?

GATE 2023 Exam is conducted by IIT Kanpur in February. IIT Kanpur released all the official GATE 2023 notifications in June 2022, including GATE Exam Date, GATE Exam Pattern, and GATE, GATE Syllabus. GATE 2023 will be held tentatively in the month of February across various cities in India.

GATE Exam is conducted at the national level, and every year around nine lakhs candidates appear for GATE Exam. Hence, it is very important to crack the GATE 2023 Exam. GATE Score holds a high weight-age because IITs, NITs, IISc, and IIMs consider the students with a high percentile in GATE 2023 Score for their admission process.

The GATE Syllabus 2023 is essential as it helps the students understand the subjects and topics covered for the GATE exam. Qualifying for the GATE Exam 2023 is vital for the students. It will determine their admission and financial aid to Postgraduate Programs (Master’s and Doctoral) with the Ministry of Education (MoE) and other Government Scholarships, depending on the admission criteria of the admitting institute. Meanwhile, some PSUs (Public Sector Undertakings) also consider the GATE Score for their recruitment. At the same time, several other universities in India and abroad establish their admissions on students’ performance in these exams. Therefore, comprehending the GATE Exam Syllabus will help students plan their studies accordingly to ace the exams.

How to crack GATE 2023 Mechanical Engineering?

A full-proof strategy is required for thorough preparation before the examination. Only the knowledge of the subject matters won't be enough to crack GATE Mechanical Engineering. It's also crucial to acquire professional knowledge and be confident enough that they can tackle any problem in all these subjects.

Step 1- Know the GATE from every aspect

It is frequently found that the GATE candidates appear in the examination without having the knowledge of the system and pattern of the examination fully. GATE examination is a single paper examination that is conducted online. It is a three-hour examination where the applicants have to answer 65 questions carrying 100 marks. The paper consists of MCQs and Numerical Answer Type questions.

Step 2- Know the GATE syllabus in detail and the weight-age of each subject

We have discussed the syllabus of GATE Mechanical Engineering in this blog. Though the weight-age on each subject is not precise, candidates need to assess the same from the previous years' question papers. Knowing the probable weightage on each section will help the candidate appearing in the examination to prepare accordingly.

Step 3- Preparation strategy

The preparation strategy varies from one student to another. Some students ask how to prepare for GATE Mechanical from the 3rd year or before. These students are serious and want to crack the exam with hard work and proper preparation. We at Ace Online provide you with a complete strategy to help finish the syllabus with a plan.

Step 4- Revision & Previous year papers

Candidates should give equal time to revision after Preparing the topics. Previous Year Papers provide a fair idea about the question pattern of the exam. This website will provide you with all the previous year's papers, and you can quickly solve them by tracking the time limit.
