The exam for Junior Engineer - SSC JE is conducted every year and thousands of posts are announced and so many candidates apply for these posts OF SSC JE. Mechanical Engineering is also the part of SSC JE Exam. A quality preparation strategy for SSC JE exam can lead you towards your goal of clearing the exam. The SSC JE Mechanical Engineering paper mainly consists of theoretical questions. Around 80% of paper is based on theory so, you need to prepare very well for the Mechanical Engineering questions. Cracking SSC JE needs dedication and a great level of preparation strategy. Make a study schedule, stick to it and be true to yourself.
Includes 83 docs & 63 tests
1. Know the syllabus and Pattern:
The first step in the preparation is to be very thorough with the syllabus for SSC Mechanical Engineering exam for the post of Junior Engineer(JE). You should know the pattern of questions asked. The syllabus will help you know what topics are easy for you and which might need some extra attention. But, make sure to cover all subjects and topics under Mechanical Engineering since you never know which subject will be asked for more marks.
2. Focus on Basic and Theoretical Concepts:
To be able to attempt all kinds of questions with ease during the exam, your basics need to be very strong. You will be able to learn the higher level concepts only when the fundamentals are clear. As around 80% of the paper is based on theoretical concept, therefore focus more on understanding the basic theoretical concepts. Also the Questions can be asked in a twisted way so if your basics are strong you can easily answer them.
3. Prepare a Study Plan:
You need to manage your time and allocate required amount of time to every subject. Prepare a proper timetable and follow it strictly so that you are able to cover the whole syllabus without missing any topic. Time management is also necessary during the exam. The SSC JE Paper I exam will be of 2 hour. So try to save your time from the Technical Section (i.e Mechanical part) & use it in Reasoning section as it will help you to fetch more marks. Also, the General Awareness section is easier & less time consuming as compared to Technical section so you can easily boost your scores here.
4. Revision - A must:
As you study every subject, make notes simultaneously. This way you will be to learn faster and also, these notes will be useful during revision. It will help you in revising the topics that you have covered till now. You can go through these notes if you get stuck on any chapter or any doubt arises in your mind regarding the topic you have studied till now. Also you can use these short notes before 2-3 days of exam for revision purpose.
5. Test yourself With Mock tests and Previous Year Papers:
Taking tests and evaluating yourself is very important in order to retain all the concepts in your mind for a long time. It is very important to measure your preparation level. So keep a track of your progress daily by attempting a full length SSC JE mock test. Also, allocate time wisely and test yourself regularly on your speed, proficiency and concepts.
Attempt SSC JE Previous Year Question papers to know the pattern of the paper. Also, with lots of practice, you will know your weak points and strengths and hence, you can improve on your weka areas.
