UPSC Preliminary Examination Strategy

About Prelims:

Preliminary examination is the first and very important stage of the three stages of the Civil Services Examination.

Structure of Preliminary Examination

The Preliminary stage consists of two papers : General Studies Paper I and General Studies Paper II. General Studies Paper I consists of 100 questions of 2 marks each which is to be answered in 2 hours.

Cut-off depends on the comparative performance of candidates appearing in the examination each year. By the year 2014, the cut-off was based on combined marks of Paper I and II, but from 2015, CSAT was made
with 33% marks. Now, cut-off is based only on the basis of Paper I.

Preliminary Examination Right Strategy:

  • Every individual is unique, Every individual is talented, and Every individual has immense potential' UPSC requires a generalist for serving the highest echelons of administration in India. A generalist is someone who knows something about everything, but not everything about something (called scientists or researchers).

  • Your approach while reading should be somewhat like a generalist, i.e. jack of all trades master of none.

  • For example, if you are reading about floods, you should focus on understanding their causes; implications (+ve and –ve) – impact on human property and life ; their mitigation and management. You need not read scientific literature about floods, river flows, meandering etc. At most, read what they are and how are they related to an earthquake.

  • In fact, success in the CSE does not depend only on diligence as it relies on your skillful methods for quality learning.

  • Most of the candidates think of working hard only, but it is combination of hard plus smart work that would pay in this examination.

  • All the aspirants do not belong to the same academic, economic and social background so their strategy also differ but for the final success in this examination, the candidates have to undergo the same process and pattern of the examination. So, even if the strategy will be different the paradigm must be kept high.

  • In the prelims Ist Paper (merit deciding paper) 100 questions are asked, so the strategy has to be made such that one can correctly solve solve upto 70-80 questions.

  • You can clear the Civil services Prelims in one shot. You don't even need to know everything under the sky. You should read with the approach of a generalist. Understanding concepts should be the first priority because mugging up neither helps you in Prelims nor in Mains. So focus on basic understanding; and wider coverage rather than detailed studies and intensive coverage.

Total 100 100 100 100 100 100 100

It is clear from the above table that there is a significant difference in the number of question is being asked in each section in each year. For example, you see that about 16- 18 questions were being asked in the Geography from year 2011-15 whereas in 2016, only 3 questions have been asked. Same as in the Current Affair sections only 5-6 questions were being asked in year 2011-12 whereas in 2016, 37 questions have been asked. It is completely clear that under sectional study, we cannot ignore any of the section but there is a need to give sufficient emphasis on all the sections.

Just remember these few things for efficient and effective studies:

  • Don't read a book from Cover to Cover.
  • Don't make notes in the first reading itself.
  • Keep your booklist short and simple. Better to read one book for each topic thoroughly, then flip through multiple sources.
  • Read carefully and between the lines since Prelims questions can be tricky.
  • Preliminary Exam is all about 'identifying' the correct answer among the 4 options given. So don't worry about remembering facts for the exam. It's all about elimination of the wrong options and identifying the correct one. Focus should be more on understanding the concepts.
