GATE CIVIL ENGINEERING PREPARATION TIPS
1. To start with, candidates must be aware of the GATE exam pattern for civil engineering completely
- It 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 Civil 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 Civil 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.
