Here are some indispensable strategies for “How to Prepare Mechanical Engineering for GATE-2017”

The (Graduate Aptitude Test in Engineering) GATE-2017 will be held in the month of February-2017.The Dates of exam though tentative but have already been disclosed in the notification given GATE authority. This time the exam will be organised by Indian Institute of technology IIT-Roorkee. The Exam is conducted all over India for Engineering and Science graduates for entrance to Post graduate courses. Around 1 Furthermore the Public Sector Units (PSUs) also select candidates based on their GATE score. Here we are providing a series of posts dedicated to preparation strategies for various branches.In addition this post is dedicated to Mechanical Branch.

The GATE Examination – 2017 is conducted in Twenty Three (23) branches and the branch codes as mentioned below- AE, AG, BT, CE, CH, CS, EC, EE, IN, ME, MN, MT, PE, PI, TF and XE AR, CY, EY, GG, MA, PH and XL

So in this posts we will discuss important strategies to crack GATE – 2017 from Mechanical Engineering Branch and How to Prepare Mechanical Engineering for GATE-2017 . Furthermore, the Candidates with various correlated branches with mechanical engineering have to appear GATE-2017 from Mechanical Engineering branch only.

First of all, Let us observe the pattern of GATE Examination -2017. There will be total of 65 Questions worth 100 marks which are to be attempted in the Duration of stipulated time of 3 hours.In addition there will also be the provision of negative marking i.e .33 mark for 1 mark questions and .66 mark for 2 marks questions respectively. The Given below is the exam pattern of GATE-2017 for mechanical branch in the Tabular form-

Its a great step to go through syllabus and it is very important to follow this way. This will give an edge and will help in understanding the idea of which topics to excel and which topics to skip. This gives a support to adopt a selective study to prepare for exam. Here are some strategies to have an edge on preparation and How to Prepare Mechanical Engineering for GATE-2017. Therefore, sticking to these strategies will make preparation smooth and faster.

Strategies to crack GATE-2017

1) First of all go through the detailed syllabus of Mechanical Engineering. Select your subjects accordingly i.e those subjects which carry more weightage are more important for exam. Do analyse what exam wants from you (Mechanical Engineer).

2) Focus more on core subjects. For Mechanical Engineering subjects like Machine design, Thermal engineering Manufacturing science & Engineering are must. These subject carry more than 50% of Weightage of Technical Subjects.

The Priority of Subjects should be –

Mechanical Engineering
Design of Mechanical Equipment or Machine Design
Thermal Engineering
Manufacturing Science & Engineering
Production Engineering
Industrial Engineering
Material Science & management

3) Prepare short and smart notes using Standard textbooks like Dr. U.C. Jindal, Buffa&Sarin etc. or get enrolled in good coaching if self study is not possible

4) The Most important Pillar of Preparation  is “Previous Years Questions” . Do Practice previous year questions as much as possible. This will let you know the level of Questions asked in the GATE examination. Furthermore, it will guide in judging the evolving nature of Exam.

5) Do Make a short List for Various Formulae and keep it handy so that you can revise it periodically.

6) REMEMBER REVISION OF PREPARED TOPICS IS MORE IMPORTANT THAN FURTHER PREPARATION!!!

7) Frequently Practising Mock Test is another Important part of preparation. It acts like a Garnishing agent in the preparation.Do stick to a good test series. This nourishes our exam preparation and readily helps to experience a real time exam mode.

8) Set target of completion of syllabus and keep 1 month for revision of exam. Consistent revision of subjects help in mastering the subjects quickly.

Best of Luck of Exams!!
