What is GATE?

The Graduate Aptitude Test in Engineering (GATE) is an All-India examination administered and conducted in eight zones across the country by the GATE Committee comprising of Faculty members from IISc, Bangalore and other seven IIT’s on behalf of the National Coordinating Board, Department of Education, Ministry of Human Resources Development. The GATE score/rank is used for admissions to Post Graduate Programmes (ME, M.Tech, MS, Direct Ph.D.) in institutes like IITs and IISc etc with financial assistance offered by MHRD. PSUs too use the GATE scores for recruiting candidates for various prestigious jobs with attractive remuneration.

In GATE examination, candidates can apply for only one of the 23 papers listed in the table given below. Candidates are expected to appear in a paper appropriate to the discipline of their qualifying degree. However, candidates are free to choose any paper according to their admission plan, keeping in mind the eligibility criteria of the institutions in which they wish to seek admission. For more details regarding the admission criteria in any particular institute, candidates are advised to refer to the websites of that particular institute.

Why GATE Petroleum Engineering was Introduced?

GATE is considered to be the standard examination conducted not only for post graduation admissions but also to open the gates for lucrative opportunities in several public sector enterprises i.e., ONGC, IOCL, MECL etc. Based on the score achieved in GATE, admissions are offered in IITs, RGIPT and abundant opportunities for campus placements. Candidates on qualifying GATE, get a financial aid in the form of UGC scholarship.

Students interested in management can swing in the management line by pursuing a PG Diploma of 2 years in Industrial Engineering. Some institutes in India also offer admissions in the post Graduate programmes on the basis of GATE score.

What is the GATE Petroleum Engineering EXAM Pattern?

  • The GATE exam consists of a single paper of 3-hour duration that contains 65 questions carrying a maximum of 100 marks.

  • The GATE question paper will consist of both multiple choice questions (MCQ) and numerical answer type (NAT) questions.

  • The Tests for all the papers will be carried out in an ONLINE Computer Based Test (CBT) mode where the candidates will be shown the questions in a random sequence on a computer screen.

  • Candidates are required to select the answer (for MCQ type) and enter the answer for numerical answer type question using a mouse on a virtual keyboard (keyboard of the computer will be disabled).

  • Each candidate will be provided with a scribble pad for rough work. The scribble pad has to be returned after the examination.

  • At the end of the 3-hour window, the computer will automatically close the screen from further actions.

What is the marking scheme of GATE Petroleum Engineering Paper?

  • All papers will have 65 questions for 100 marks in total

  • All papers will have a compulsory section on General Aptitude with 10 questions carrying a total of 15 marks.

  • Paper will have a compulsory Engineering Mathematics section that will carry around 15% of the total marks. The remaining 70% of the total marks is devoted to the subject of the paper.

  • Negative marking will be only for the multiple choice questions (MCQs). For 1-mark multiple choice questions, 1/3 mark will be deducted for a wrong answer. Likewise, for 2-mark multiple choice questions, 2/3 mark will be deducted for a wrong answer.

  • There will be no negative marking for a wrong answer in numerical answer type questions

Which types of questions are asked in GATE Exam?

  • Recall: These questions are based on facts, principles, formulae or laws of the discipline of the paper and test the candidates on their memory or deductions skills.

  • Comprehension: These questions test the candidate’s understanding of the basics concepts of their field and require them to derive the answers by drawing simple conclusions from fundamental ideas.

  • Application: In these questions, candidates are expected to apply their knowledge either through computation or by logical reasoning.

  • Analysis and Synthesis: For these questions, candidates are presented with data, diagrams, and images. They must analyse these and answer the questions.

How to Crack GATE in Petroleum Engineering?

GATE 2021 will be conducted by IIT Bombay in online mode. Below are the few tips on how to prepare GATE in Petroleum Exam. The  journey of preparation for GATE 2021 petroleum engineering requires a proper strategy, a concrete plan and serious efforts. Serious Preparation is the most crucial phase for the GATE exam and thus, we have tried to make the preparation simpler by jotting important steps to crack GATE in Petroleum Engineering.

  • Strategy

For any exam first thing that should come into the mind of aspirant is a proper strategy, both for preparation as well as the D-day. Candidates are advised to prepare their own time table and adhere to that time with full concentration. Candidates can divide number of hours depending upon their grasp on the topics. While preparing and understanding they should prepare short notes on the go, this makes revision handy and candidate can revise many topics in one go using short notes. 

  • Grasp the concepts

Many students kick start their preparation by cramming and memorising i.e., memorising important correlation, unnecessary formulas. But GATE is not an exam based upon how many formulae aspirant has memorised i.e., it doesn’t check memory of aspirants. Aspirants need to have understanding and practical approach of all the concepts. Say for example: In Reservoir engineering there are many gas correlations but students need to understand those correlation instead of cramming it up. There are many concepts in relative permeability curve, a thorough understanding is required for the same. Thus in depth understanding is must when it comes to concept of GATE in Petroleum Engineering.

  • Prepare Mathematics and Aptitude

Above two subjects cover 30 marks out of 100 marks in GATE Exam and they are scoring too. These two subjects are non-technical and requires minimum effort to prepare thus practise as much as you can and even an average student can score 25+ marks out of 30. Thus these topics shouldn’t be underestimated else you may end up losing few bonus marks. 

  • Books

As there are many books to prepare GATE in Petroleum Engineering but fundamental concepts remain same in all the books. Thus in order to remove confusions we have prepared 18 recommended books for gate in petroleum engineering. 
Note: Aspirants need not to buy the hard copy of these books, the e-books of the same can be downloaded from our telegram channel(@gateaiotspe).

  • Technical acumen

As petroleum engineering is an applied engineering and it required in depth knowledge of various engineering and science concepts. Thus students should be focusing more on core concepts of topics like Reservoir Engineering, Drilling Technology, Production Technology etc. 

  • Revision

As revision is the key to crack GATE exam. Aspirant should prepare short notes, mnemonics and highlight pdfs paragraphs while preparing the topics. it makes revision less cumbersome with time and more effective. Revision is no less than second reading and it boosts confidence level of students with time.

  • Practice Past Question Papers

Only reading and revising the fundamental concepts is not enough while preparing for GATE in petroleum engineering, aspirants should also assess and analyse the level of their actual preparation and knowledge. For that, previous GATE question papers should be practised. This will help the aspirants to assess the marking pattern and level of difficulty of GATE paper and thus will prepare them to adjust their preparation strategy. 

  • Mock Tests are Important

One of the best methods to prepare for an examination is to appear in online mock tests. Mock tests help aspirants to find their mistakes and accordingly aspirants work on them. Aspirants can join GATE 2021 mock tests to understand their preparation progress curve. The mock tests acts as a simulation for the actual GATE Exam since the quality and pattern of the questions will be inline with actual GATE Exam. 

“GATE AIOTS PE Test series helped me to regularly simulate my studies through part tests and helped me to correct my mistakes. The confidence that I got after some good part test helped me to move further.” says Sachin Jain (GATE 2020, AIR 2 -Petroleum Engineering)
