As can be seen from the pattern of exam, paper 1 of the preliminary examination consists of General Studies and Engineering aptitude which is common for candidates of every stream. This paper is of 2 hours and carries 200marks. The syllabus for this section is mentioned below with all the necessary details:

1.     Current issues: This topic is one of the most important and the toughest of all as you cannot master current affairs in just a month or two. For the current affairs make sure to read the newspaper (The Hindu/ Indian Express) daily and makes notes of the important GS For revision you can also pick up a monthly magazine published by a good institute at the end of the month. The current issues section is mainly concentrated on topics related to the matter of national and international importance relating to social, economic and industrial development which one can only know if he/she is aware of what is going around by being regular with the newspaper. Near about 10 questions from this area, makes it important to study. By studying this you are simultaneously grooming yourselves for the interviews, where they may ask you some questions related to current affairs.

2.     Engineering Aptitude: This section covers logical reasoning and analytical ability. Like the CAT paper, you don’t have to practice this session every day for long hours. The questions in this section are very basic in nature mainly class 6 to 8 Try practicing these questions once a week from the internet or pick up any basic Arihant book on logical reasoning and analytical ability. You can also refer Engineering Aptitude and Reasoning book of MADE EASY Publication which has concepts as well as solved questions of aptitude section of six branches (CE/ME/EE/EC/CS/IN). While practicing if you face any difficulty remember to make notes of the important formulae being used and make sure to revise them regularly.

3.     Engineering Mathematics and Numerical Analysis: Comprising about 7-8 questions from this section; a student is required to revise the subject at regular intervals. This section if revised nicely can fetch you full marks as well. This area is basically from M1, M2 and M3 maths which every engineer studies in their first and second year. So, it is a section where you know things and you have the basic idea only thing is you need to brush up concepts for extra scoring. MADE EASY has published a special book for the students which elaborately covers all the topics along with examples to help the students gain expertise on the subject. Check out our book at https://bit.ly/2tsOCT4

4.     General Principles of Design, Drawing, and Importance of Safety: First get acquainted with the syllabus of this section and if you are not very comfortable with the designing questions, try concentrating more on the safety part which has 4-5 questions. For Designing and drawing, Mechanical students may have an upper hand as they study it for 2 years so you can always take help from your friends. Further, every engineering student has studied this subject in their first year, the only thing is you need to have that imagination and concepts to visualize the plan and elevation of different geometries. This can be easily achieved by learning concepts and then practicing questions. There are also many books available in the market for the subject and a brief look through the book can help you with this subject.

5.     Standards and Quality: This subject too is common with the industrial and production branch so you can take help from your friends. Another method to approach this topic is to go through the previous year papers and make sure to revise the important topics so that you do not miss out completely on this section which has about 7-8 questions. You can always take help of a good coaching institute by referring to their study material.

6.     Basics of Energy and Environment: This is an important subject of Paper 1 as it covers some 12-13 questions. While covering current affairs makes sure you give special emphasis on the energy and environment part as well, as it will come in handy in covering this subject. Normally the questions are static but are indirectly related to the current affairs. Therefore, whatever is in the news make sure you are thorough with its static part as well. Along with the current affairs, you must pick up some good environment book from the market published by a good coaching institute as it would reduce your task of looking out for the important topics. The study material will comprehensively cover all the topics.

7.     Basics of Project Management: Similar to Designing and standards topic this topic is common with civil engineering syllabus and mechanical engineering syllabus so help from friends will come in very handy. As a supplement, you should always pick up a book from the market from any good coaching institute that covers all topics in detail without missing out on anything.

8.     Basics of Material Science and Engineering: This subject covers some 10-12 questions and as we all have studied this is in the first year of our college, the subject wouldn’t be very difficult for any student. All you need is to go through all the topics again and remember this with ease by picking up a comprehensive book on material science from a good coaching institute. This generally covers easy topics like mechanical and electrical properties of the materials, ferrous and non-ferrous alloys, polymers, composites etc. which are easy to understand and interesting to study.

9.     Information and Communication Technologies (ICT): This subject has some 8-10 questions and most topics are covered in the current affairs section itself. Reading the newspaper attentively will help you gain confidence in this section as most questions are current affairs based. Again as a supplement, you can always pick up a book from the market to clear any doubts you have about what is in news and understand the concepts and topics better.

10.  Ethics and values in Engineering profession: Covering some 8-10 questions, ethics and values is something that comes naturally to a person and cannot be taught. This section tests your managerial skills and doesn’t require much bookish knowledge and deep studying.

All the Best
