the objective type question papers
- There are four alternative for the answers to every question. For each question for which a
wrong answer has been given by the candidate, one-third (1/3rd) of the marks assigned to
that question will be deducted as penalty.
-
If a candidate gives more than one answer, it will be treated as a wrong answer even if one
of the given answers happen to be correct and there will be same penalty as above for that
question.
-
If a question is left blank i.e. no answer is given by the candidate, there will be no
penalty for that question.
3.1 The Engineering Services (Main/stage-II) Examination will consist two conventional type papers in
Engineering Discipline specific with duration of three hours and maximum marks of 600 (300 Marks in each

Preparation strategy for UPSC Engineering Services Examination
IES is among the most prestigious and coveted career options that are available for engineers
encompassing private, public and government sectors. Just like the Civil Services, the candidates
recruited for the IES are highly honored by the government and the society.
Since there are many opportunities for engineers in the public sector like Indian Railways, Central
Engineering, Military Engineering, Telecommunications, Central Water Services and many other
departments, the IES is a highly desired job where candidates get to play an important role in the
development of the country.
The keys to success in the IES or any other exam will always be hard work, relentless efforts and
perseverance. However, a smart approach involving systematic planning is also crucial to achieve
targets. A thorough knowledge of the subject including clarity of basic concepts along with
awareness about current affairs, general knowledge add to the advantages of hard work. A smart and
mature persona is also a prerequisite for successfully cracking this exam.
You can use these tips to get a fair idea of these exams and develop your own personal strategy:
You must understand and acquaint yourself with the latest pattern and syllabus of the examination.
The previous year's question papers can be a great help. You can screen them thoroughly to identify
the repeat topics and questions and prepare accordingly.
Use reference books to understand concepts but prefer to understand one topic from one good book to
avoid confusion and waste of time. However, you can use different books for different topics.
Time management is a very crucial factor during preparation and even writing this exam. One must
chalk out a proper strategy and time table. Each subject from the technical section must be devoted
at least 3 hours daily to get best results. English and General Studies should also be given 1 hour
each so that you can get a cutting edge in exam.
To avoid boredom and maintain enthusiasm distribute the subjects well in your time table for
studying. You can alternate between General Ability and Technical sections to make studying
enjoyable.
You must segregate short-term and long term study goals, and work accordingly to succeed.
Short notes are very helpful especially in technical subjects. Make short notes of important topics
and also a list of formulae and revise them daily.
Practice of questions helps to assess your understanding and level of concepts. Practice as many as
possible from books and previous question papers..
Since time is a crucial factor while attempting the exam candidates can time themselves while
practicing questions. Ensure to complete the tasks within the stipulated time.
Candidates can also practice questions with the help of OMR sheets so that they get acclimatized to
using them during the exam.
For English, you can learn 20 new words daily from previous years question papers or other sources.
You can also solve 10 to 15 questions of English daily, based on rearranging sentences and finding
errors.
Reading the newspaper, watching the news, surfing the net will help to prepare for the general
ability exam. Knowledge of Current Affairs of 45 days prior to the exam will help to sail through
this exam..
Daily practice of at least of 5 questions from the previous year papers of conventional exam will
enhance writing skills and presentation.
Practice of mock tests that include all sections of the exam within a limited time frame will help
you to sail through and succeed in these exams.
Time plays a very crucial role during all exams including the ESE. So, it is a must that you
optimally utilize the allotted time.
There are 120 questions in Objective Paper I, evenly based on General Studies and English. Since
Comprehension and questions based on rearrangement of sentences are time consuming, candidates can
solve those after completing the rest of the exam.
Ensure that you read the Comprehension thoroughly before attempting the questions. This will give
you a better idea for answering correctly
Attempt the questions you find easy before moving on to the difficult ones.
Technical theory questions are best attempted before the numerical since you may take long to
attempt
numerical which also carry negative marking, so a well attempted theory gives you stronger chance of
scoring well and covering up for negative marks
Remember to write the formula in the numerical problems, along with S.I units of quantities involved
and also specify the answer.
There are two conventional papers on the third day. Attempt the easy questions first after reading
the paper thoroughly and keep the difficult ones for the end.
Make sure the presentation of your answer sheet is neat, systematic and well organized with properly
labeled diagrams if required. An orderly answer sheet with exact expression within proper word limit
is credited for especially in the conventional papers.
Consistency, Perseverance and self motivation are the key ingredients of success.
Enhance your memory power and efficiency by indulging in recreational activities, to keep your mind
healthy and rejuvenated.
Keep the documents related to examination such as hall ticket, acknowledgment of application,
application number and other details safely to avoid any hassles.
The last day before the exam must be spent in relaxing and revising only important topics and notes. You
must also sleep for at least 6 hours to wake up fresh and rejuvenated for the exam.
Remember to carry sharpened pencils, pens, eraser and your hall ticket on the day of the exam.
Make sure that you reach the exam centre well before time and avoid studying during traveling.
PREPARATION STRATEGY
Preparation for the ESE requires both, clarity of concepts as well as problem solving skills, since
the written exam has objective and subjective sections. A few key points will have you sailing
through.
Begin with awareness of exam pattern, percentage of technical questions & non-technical ones,
weightage of each section to streamline your studying strategy. Use Previous year question papers as
guide to make smart decisions regarding your study plan.
Use Reference books for understanding theory, concepts, derivations and equations etc. and make your
basics strong.
You can practice previous year question papers to analyze your weak areas. Identify the weak topics
and revise them thoroughly. Time yourself as you solve the papers to get an idea of your speed so
that you can focus on that too.
The General Ability section carries 200 marks and is important even for the Personal interview. Keep
your General Knowledge updated for this section through news papers, news channels or surfing
websites.
Writing the Exam
Smart writing skills, good presentation, proper explanations, theoretical reasoning, derivations,
related equations and diagrams will help you cover the subjective section.
Short Cut Techniques: Solve numerical using short techniques rather than traditional methods to save
time.
Beware of marks per question, negative marking and exam duration while attempting the paper.
Personal Interview Your all round personality is the focal point of personal interviews. A
Positive
attitude, Smart body language, Proper communication and Knowledge about current affairs reflect a great
Persona. Along with this Sound technical knowledge can create a great impression in personal interviews.
You must prepare to answer queries about your strong and weak traits.
