GATE

**Some of these Professional Societies / Institutions, which conduct examination in various fields of engineering, are as follows.

• The Institution of Engineers (India) (IE)
• The Institution of Civil Engineers (ICE)
• The Institution of Electronics and Telecommunication Engineers (IETE)
• The Aeronautical Society of India (AeSI)
• The Indian Institute of Chemical Engineers, including Polymer and Environmental Group (IIChemE)
• The Indian Institute of Metals (IIM)
• The Indian Institute of Industrial Engineers (IIE)

However, the candidates who possess certification from any of the professional societies must ensure that those examinations conducted by the societies are approved by MHRD/AICTE as equivalent to B.E./B.Tech./B.Arch, subject to public notice (Advt No.P& AP/10(04)/2017

GATE examination consists of Multiple Choice and Numerical Answer type questions.

Multiple Choice Questions (MCQs)

These questions are objective in nature and each question will have choice of four answers, out of which the candidate has to mark the correct answer. Each question carries 1 or 2 marks in all the sections.

Numerical Answer Questions

There will be no choices available for these types of questions. A Numeric Answer question carries 1 or 2 marks questions in all sections. The answer for these questions is a real number to be entered by using mouse and virtual keypad displayed on the monitor. No negative marking for these questions.

Preparation Strategy –

1. The most important part of preparation for GATE is to go through previous 15–20 years question papers and find out what should be your Subject priority list. I have given the weightage for different streams below.

                       Civil Engineering GATE 2018 Session 1 Analysis

                 Civil Engineering GATE 2018 Session 2 Analysis

Mechanical Engineering GATE 2018 Session 1 Analysis

                               Mechanical Engineering GATE 2018 Session 2 Analysis

2. Once you have decided the subject priority list, start your preparation accordingly. Decide the time for each & every subject.

Go through the class notes and try to solve previous 15 years questions for that particular subject. While solving questions, if you find that some topics are not covered in your class notes, refer only that part in a standard reference book of that particular subject. Dont read the entire reference book if you have attended all your classes regularly.

4. GATE is formula oriented conceptual exam. Looking at the scores past 3–4 years,competition is tough. I will suggest that dont leave anything for option. Study every subject thoroughly and each & every topic. Byheart all the formulae and understand the concept behind that formula.

Smart study techniques –

• Prepare short notes for each and every subject. This helps in last minute preparation just before 30–40 days of exam. In the last 30-40 days, revise short notes and solve the numericals which are most critical and important.

How to prepare short notes?

While preparing short notes, dont include everything. Include just important key concepts and Formulae.

2. While preparation, dont study single subject for the entire day. Take atleast 2 subjects simultaneously for preparation. This will keep your interest level up and you will not get saturated while preparation.
3. In the last days of preparation, Avoid studying new concepts & formulae. Focus only on what you have studied entire year.
4. Make charts and shortcut tricks to memorize things easily so that during exam, you can recall and recollect at ease.
5. Join online and offline test series at IITians Academy. (Subjectwise & Full length mock tests)
6. I have seen candidates getting disturbed and leaving their regular studies due to bad performance in test series.

Note : Test series is not going to decide your rank in the final exam of GATE. Test series will help you to know, Which areas you are perfect and Which areas you need to focus more on. Dont compare yourself with others in test series. Compare your own performance in the previous tests given by you.

7. Most important part of Preparation is Revision. Revise on regular basis so that you dont forget and you will be able to save much of your time by timely regular revisions.

8. Time table

Prepare a proper study plan which should be balanced from all perspectives. Dedicate atleast 10–12 hours for your preparation. As told earlier, study atleast 2 subjects simultaneously.

9. Hard Work & Self Motivation

This 2 things will decide your future through GATE. Be self motivated and keep working hard. Have trust in your abilities. Stay focussed. Stay true and honest to yourself while preparing. Decide your priorities in Life.

If you succeed, Success is entirely yours and no one can take that credit from you.

If you fail, Failure is entirely yours and you cant blame anyone for that.
