STRATEGY FOR HANDLING CSAT PAPER

In 2011, UPSC has introduced the CSAT paper as paper-2 in upsc preliminary examination. In this paper, total 80 questions are asked from General Mental Ability, Data Interpretation, Reasoning and Analytical Ability, Decision Making & Problem Solving and English Comprehension. However, there is a change in the trend of CSAT paper in terms of the toughness level of questions has been increased. A student needs a comprehensive approach to clear the CSAT paper in an easier way.

There is an approach to handle it easily. As you must be aware you need only 33% (66/200) in the CSAT exam and you do not have time to devote to CSAT as GS paper 1 required a lot of hard work. What you can do that take UPSC previous papers of CSAT and solve them in entirety to understand the demand and spirit of the subject. Learn the logic used in the solution to solve the problems. After solving these papers take 5–6 mock tests of any coaching and solve them. You will get an idea about how much you are scoring and where is the scope of improvement. Afterward, you can focus on that particular area, for example, Mathematics or English or Logical Reasoning.

SOURCES FOR PRELIMINARY EXAMINATION

The list of mandatory sources to be followed has been mentioned with each section of the syllabus.

Now one important thing comes is when you are preparing for the UPSC Civil Services Examination, NCERT books play a crucial role in your preparation. In hypothetical language, these books are the backbone of your preparation. UPSC asks questions based on basic concepts and fact directly or indirectly. NCERT books help Civil services aspirant to get his/her basic concepts clear. The best way to read NCERT books is by assuming yourself a school student. It will help you to relate the things and will make you more comfortable while reading these books. Most of the candidates take it on the ego that I am a graduate and why should I read this 6th class NCERT book. Hence, you are requested to avoid this approach.

THE INTEGRATED APPROACH OF PREPARATION

Integrated approach is the best upsc prelims strategy to prepare for both prelims and mains exam in one way. To develop this approach please keep the syllabus of prelims as well as mains in your mind. Find out the common topics like History, polity, geography, economy etc. First prepare these subjects in a way that you can solve objective question from these topics and you can write a subjective answer also if asked.

For this have a look on previous year prelims and mains papers to build a clear idea about the exact requirement. Make the list of common study sources, complete them first and them go to the mains specific topics like ethics, word history etc. 

LAST MONTH TIPS FOR PRELIMINARY EXAMINATION

The last month is crucial for preparation. The last month tip would be-

  • Do not focus only on covering the syllabus but start revising the stuff. One month before Preliminary Examination, you must be focused on revising current affairs part because you have presumably been studying the static part for at least one year.
  • Try to solve mock papers and try to find out your strong and weak areas. Analyse test and work on your weakness.
  • Read all the important NCERTs thoroughly and highlight important points. Revise them maximum times.
  • Refer to previous years' question papers for General Studies paper 1 and try to get insights about the pattern of questions being asked. Once you get an idea about this, focus on such areas while studying.
  • Make notes out of the newspaper which you follow regularly. Refer to Chahal academy’s monthly magazine and incorporate additional points in your notes.
  • Purchase the mock tests from the market and solve at least 25–30 mock papers. Analyse your performance and work accordingly.
  • Although the CSAT is qualifying in nature, the basic level of preparation necessary. Solve previous year papers of CSAT. Solve 2–5 CSAT mock tests to feel confident in this paper.

ROLE OF MOCK TESTS FOR PRELIMINARY EXAMINATION 

Mocks tests crucial in all the three stages of the exam. For Prelims, giving a lot of mock tests will help you refine your strategy to maximise your scoring. For some answering, only those questions which they are absolutely sure of will do the trick. Whereas for someone else maximizing the number of attempts may help clear the cut-off. And there is only one way to find out the strategy that will work for you, do umpteen number of mock exams. 

Join a test series and try to solve practice papers at home in time bound manner. You are suggested to test yourself at regular intervals. Additionally, you will realise areas in a particular subject where you need to work upon. Try and solve as many test papers as possible.

 LIST MINUTE TIPS FOR PRELIMINARY EXAMINATION

  • Check and arrange the list of things you need to carry to the exam centre, like Admit card, One Id proof, Blackball pen, one photo to avoid any unforeseen thing, Water bottle etc.
  • Stay calm. Pressure takes a huge toll during those crucial 2 hours. Have faith and confidence in your preparation and follow a “mission mode approach”.

STRATEGY for handling the GS Papers

In order to excel in G.S. and mould the change in the syllabus in your own favour, what is needed is a comprehensive and strategic preparation covering all the dimensions of the syllabus well. The preparation especially for the newly introduced CSAT paper should be elaborate covering all sections well rather than focusing only on few specific areas. The emphasis should be on a comprehensive preparation, doing justice to each and every topic of the syllabus.

The G.S. and the CSAT papers, therefore, are not a tough nut to crack as such. They can be handled with much more ease provided the preparations are done in a systematic and strategic fashion. The Wizard's Strategist for GS can be an excellent guide in this regard as it provides you the pattern and the trend analysis of questions asked in previous years.

Let us look into the subject-wise breakup of GS Papers.

Polity


Of late, the importance of 'Indian Polity' has increased tremendously in Preliminary and Main exams. It is expected that this trend will continue in future also The best part is that the questions from Indian Polity are more or less straightforward which can be easily answered with a careful study.

In polity, there are chapters from which questions are frequently being asked. These are the Constitutional Developments, FRs, FDs and DPSP, Union Government, Judiciary, Amendments, Local Governments, Federalism and Election process. Till 2000, questions on comparative government were asked. But now-a-days Amendments, Elections, Federalism and Parliament have assumed significance.

Most of the available books lack information on current constitutional developments. So, a keen perusal of newspapers and magazines is essential with a good knowledge of provisions of the Constitution. After all, chapter-wise break-up is imperative which simplifies the problem and facilitate your understanding.


General Science


It can be divided into 4 parts—Science and Technology, Biology, Chemistry and Physics. On an average, 10 to 20 questions can be expected from this section. For students with Arts backgrounds, this section is always a nightmare. But basic understanding of Science, especially a thorough understanding of NCERTs, can solve most of the questions. Ignoring this area can be suicidal for any candidate.

Science and Technology


Science and Technology have become an important section of GS since last 4 years. Questions are mainly from the developments in India.

Biology


Among the General Science subjects, Biology is the most important. Recent analysis shows that questions on General Science cover general appreciation and understanding of day-to-day science. So, observing and experiencing everyday science could be handy.

In Biology, the thrust is on Zoology. Only 2 to 3 questions are being asked from Botany, particularly from agriculture, biological diversity and plant system. In Zoology, most of the questions are related to human system and diseases. Communicable diseases and nutrition have always been significant.

Chemistry


In Chemistry, questions are comparatively less. Application part of chemistry is more important in the exam. Technical details and equations are not that important.

Physics


After a keen analysis of the Previous Years' Questions, we come to know that questions are frequently asked from the chapters like Mechanics, Optics, Heat and Thermodynamics, Electricity, Nuclear Physics, Modern Physics, Sound and the Universe.

Economics

In Economics, even though most of the questions are from Indian Economy, one has to keep abreast of International Economics that has its bearings on India.

In Indian Economy, now-a-days, most of the questions are asked from Industry, Agricultural production, Exim Policy, Money and Banking, Public Finance and Reforms. National Income and International Economic Forums constitute at least 2 questions. 3 to 4 questions are from different programmes announced in the previous and the current fiscal year. In Economic reforms, infrastructure and reform policies are to be taken care of. In Money and Banking, one has to keep an eye on Financial and Banking Reforms.

The latest trend in Indian Economy shows that the importance of this section is increasing. Moreover, most of the questions are of current nature. But these questions cannot be answered without a proper understanding of traditional areas.

Many students are really afraid of Economy. This is because of lack of understanding in basics. A good understanding of the subject can be achieved by reading Class XI NCERT book on Indian Economy.

Geography


In Geography, the thrust has been on the Indian Geography, which covers around 70 per cent of the questions.

In 'Indian Geography' a thorough understanding of physical aspects of India with a proper clarity of locations, is the minimum requirement. This will help in the economic as well as the human aspects of Indian Geography.

In General Geography, the emphasis is on conceptual aspects. A careful study of 'A Certificate Course in Physical and Human Geography' by Goh Cheng Leong is the least expected of you.

In World Geography, the emphasis is more on current developments, which can be covered by map reading while going through the newspaper.

In future, the weightage on Geography, especially Indian Geography, is expected to be more. But the beauty of Geography lies in the fact that, it can be mastered with least effort. A proper preparation of NCERT textbooks on Geography (from 6th to 12th) along with Goh Cheng Leong and regular study of Atlas are more than sufficient.

History


A decent analysis of the previous years' questions gives the impression that in the last three years, the total number of History questions has shown a declining trend. But the level of toughness has increased. Moreover, the questions are being asked from hitherto untouched areas, which have made the preparation more difficult. So, over-dependence on History may prove to be fatal for non-History background students in the future.

In 'Indian History', maximum number of questions have been asked from the Modern History section, particularly from the period between 1857 to 1947, i.e. the 1857 uprising, social reform movements, British reforms in civil administration and in the other fields, Governor Generals and Nationalist Movement under the Congress.

In Ancient India, the Vedic Age, Mauryan Period and the Gupta Period are dominating. Sultanate and Mughal periods are the most important in the Medieval India. But, Marathas, Vijaynagar and Bahmani kingdoms are getting more weightage since 2001.

The level of history questions in GS is often similar to that of Optional Paper. The conceptual questions are mainly asked from socio-economic sphere. Such questions are more often asked from Modern India. Ancient and Medieval parts are generally factual in nature.

Environment


Of late, the importance of environment has increased manifold in the Civil Services Preliminary Examination. The number of questions being asked in the Exam is increasing consistently. The trend is expected to be maintained in the coming years as well.

Current Affairs


Current Affairs is one of the most important modules in the entire scheme of Civil Services Examination because of its high utility at all the three levels i.e. Preliminary, Main and Interview. Though the number of direct questions in the Prelim Examination seems to be on a declining trend but that should not be taken as a set pattern because the trend may reverse any year. One thing which must be kept in mind is that questions from conventional areas like Science & Technology, General Science, Environment, Economics, Geography and Institutions are more current in nature which further makes this section of paramount importance.


Current Affairs is a vast area comprising of events of national and international affairs, bilateral developments, sports and personalities in various fields along with prizes and honours of highest accolade. The UN and its agencies and heads of corporate sectors which falls within the ambit of current affairs have also become important.

GS Paper II (CSAT)


From 2011, the UPSC has introduced a new format for the Civil Services Preliminary Examination. It has added CSAT in the form of GS Paper II. The total number of questions asked in this paper is 80. Out of these, questions were from General Mental Ability, Data Interpretation, Reasoning and Analytical Ability, Decision Making & Problem Solving and English Comprehension. However, we should not make the mistake of treating it as a Model Paper for next year Prelim Exam. The emphasis should be on comprehensive preparation. In the final analysis, if we categories the questions beings asked, it is found that GS can be handled with much more ease. It is not as frightening as what is projected by many. In fact this book can be an excellent guide for beginners in understanding the pattern and trend of GS questions of both papers. A successful candidate is the one who has faced the challenge with a proper planning and strategy.
