GENERAL APTITUDE-   Verbal Ability and Numerical Ability

GATE Chemical Engineering Exam Pattern

Feature Description
Exam Duration 3 hours (180 minutes)
Number of Questions Asked 65
Total Marks 100
Question Types Two types of questions asked:

1. Multiple Choice Questions (MCQ)

2. Numerical Answer Type (NAT) Questions 

Marking Scheme For 1-mark MCQs, 1/3 mark will be deducted for every incorrect attempt.

In case of 2-mark MCQs, the candidate will be penalised 2/3 mark for wrong attempt

For questions that aren’t attempted, zero marks will be awarded.

There is no negative marking for numerical answer type (NAT) questions.

Sections The question paper of GATE  will consist of three sections:

General Aptitude*

Engineering Mathematics (for XL papers it is Chemistry)*

Subject-specific section

General Aptitude: Each paper will include a mandatory General Aptitude (GA) section comprising 10 questions. 5 of these questions will carry 1-mark each, while the remaining 5 will each carry 2 marks, for a total of 15 marks.

GATE chemical engineering Exam Pattern: Key Highlights

  • GATE  has become a computer-based test that will be conducted in online mode
  • gate exam patternGATE question paper will consist of two question types: multiple choice questions (MCQs) and Numerical Answer Type (NAT) questions
  • The questions will be displayed on a computer screen randomly
  • In case of MCQs, the candidate needs to select the correct answer, while for numerical answer type, the candidate must enter the numerical answer using a mouse and virtual keyboard ( the keyboard attached to the computer will be disabled)
  • The candidate will have to complete the test in 3 hours. After the allotted three hours, the screen will automatically close down and no further action will be possible.
  • During the exam, each candidate will be provided with a scribble pad where the candidate can do all his rough work.
  • Each question paper will contain questions related to General Aptitude (GA) in addition to subject-specific questions.

The questions that will be asked may be designed to test the following abilities of the candidate:

  • Recall: Questions in this category are related to facts, principles, formulae or laws of the discipline of the paper. The aim is to test the memory and computation skills of the candidate.
  • Comprehension: These questions test the candidate’s basic understanding of his/her chosen field. The candidate is required to draw simple conclusions from fundamental ideas.
  • Application: To answer questions in this category, the candidate has to rely on his/her computational and logical reasoning skills.
  • Analysis and synthesis: These questions are accompanied by data, diagrams, and images. The candidate has to analyse the information contained in them to find the answers.

GATE CHEMICAL ENGINEERING PREPARATION TIPS

1. To start with, candidates must be aware of the GATE exam pattern for chemical engineering completely

  • gate tipsIt consists of 65 questions out of which 35 questions are of 2 marks and 30 questions are of 1 mark with a total of 100 marks. Candidates must know that there are only two types of questions, multiple choice questions and numerical answer type.
  • They should be aware that there will be 2/3rd negative marking in 2 markers and 1/3rd negative marking in 1 markers whereas there is no negative marking in Numerical answer type questions hence only they can get the maximum numbers in the test.

2. Know the syllabus of chemical engineering and the weightage

  • It is suggested that the candidate goes through the complete syllabusbefore starting the preparation. Match your knowledge with the exam syllabus and plan your preparation with known subjects.
  • Highlight the important topics in the syllabus based upon the previous year papers and focus more on these topics during the course of your preparation. 

3. Choose good books& study materials related to chemical engineering for the preparation

  • Selection of appropriate and concise study material is very important before starting the preparation.
  • Read at one book apart from the study material which is provided by your institution and your class notes.
  • Nowadays the whole package is available online in the form of video lectures, course materials PDF, so you can pursue best study material.

4. Study smartly during the preparation     

  • Analyse important topics and pattern of questions from the previous year papers which have been provided with for reference.
  • Prepare each topic in three steps. Understand the concept, practice related questions and revise regularly. This will help you to analyse your preparation and also boost your confidence.
  • Most of the questions are conceptual & numerical, so you must try to improve your solving ability and time management to score a good rank.

5. Prepare the study plan to complete the syllabus

  • The first step in the preparation is to start with easy subject and important one that has been mentioned below. Segregate whole subject into smaller topics and prepare topic wise
  • After completing the subject, make short notes for that subject which should include definitions, important formulas etc. This will help during the time of revision.
  • Clearing all the doubts during the preparation is essential.
  • Identify weak areas while practising tests and try to revise and practice those topics.

6. Proper revision plan

  • It is not just sufficient enough to prepare revision notes, but also to revise them regularly.
  • Read the revision notes on a weekly basis to recall the concepts of prepared subjects.
  • Each time you revise the same topic/ subject, your revision time will reduce to recall the concepts.

7. Mock tests and practice papers

  • Mock tests play an important role.
  • Firstly, it gives you an exam like interface. This is very important for any aspirant, to have idea and thorough practice on exam like interface.
  • They provide All India ranking, so you know where you stand.
  • Test analysis about how you performed in exam and how toppers have performed, which helps you to analyse and understand how much more preparation is required and on which area.
  • You also get to keep a check on which question was easy and you couldn’t attempt, but attempted a tough question which was expected to be left. And how much extra time have you given to that particular question.
  • Comprehensive explanation to every single question coupled with smart tricks/intuitive approach in the form of text, Images or both.
  • From mock tests, you get to know your strength and weaknesses in a well-defined manner.
  • Tests in general are important. They help not only in the assessment of your preparation for exams, but also regular test attempts help you memorize better.
