Statistics: A real game changer in Mains exam


Statistics is really a game changer in mains exam as this area is pretty much certain and do not come unexpected. If prepared properly, it can easily add 35-40 marks in your kitty without much uncertainty, though 35 marks appear to have very less weightage in 600 marks paper but its value get increased with an average score of 250 marks in GS paper. This area is feared by most of the humanities background student and often ignored by science students due to overconfidence and they end up losing marks in this important area.

One should not leave statistics unprepared and should practice it regularly to secure easy marks. One of the advantage of statistics is that the syllabus is not huge and questions are not tough as well, if concept is clear. Following is the area which is normally covered by the UPSC in exam:

1.     Statistics- Basics

ü  Definition
ü  Function & Nature of Statistics
ü  Type of Data
ü  Collection & Organisation of Data
ü  Classification of Data
ü  Grouping & Tabulation of Data
ü  Measurement scales i.e. Nominal, Ordinal, Interval & Ratio Scale

2.     Statistical Measures

ü  Measures of Central Tendency
Ø Arithmetic Mean, Geometric Mean, Harmonic Mean
Ø Median
Ø Mode

ü  Measures of Dispersion ( Absolute & Relative)
Ø Range
Ø Quartile Deviation
Ø Mean Deviation
Ø Standard Deviation
Ø Co-efficient of Variation
Ø Lorenz Curve

ü  Correlation
ü  Regression
ü  Index Numbers
ü  Skewness
ü  Kurtosis

3.     Graphical Presentation

ü  Time series Graph or Historigram
Ø One dependent variable type historigram
Ø More than one dependent variable type historigram
Ø Mixed graph
Ø Band graph
Ø Range graph

ü  Frequency distribution graph

                         Using simple frequency
Ø Histogram
Ø Frequency polygon
Ø Smoothed frequency polygon (frequency curve)

Using cumulative frequency
Ø Less than ogive
Ø More than ogive

4.     Diagrammatic Presentation

ü  One dimensional diagram
Ø Simple bar diagram
Ø Broken bar diagram
Ø Multiple bar diagram
Ø Sub divided or component bar diagram
Ø Percentage subdivided or percentage bar diagram
Ø Deviation bar diagram

ü  Two dimensional diagrams
Ø Aeral- like square, rectangular diagram
Ø Circular diagram

ü  Three dimensional diagrams
Ø Volume diagram like cubes, cylinders etc.

ü  Pie Chart

                Source of Reading

                Following books are sufficient to cover the above syllabus:

ü  Statistical Methods- S. C. Gupta ( Sultan Chand & Sons Publication)
ü Spectrum publications for practice last 5-7 years question paper on Statistics

                General Notes

ü  Understand the basics well with clarity
ü  Practice last 5-7 years question paper in the examination like simulated environment within limited time
ü  Attempt statistics in the beginning during the exam as it will avoid silly mistakes
ü  Use an original calculator and do not forget to carry it with you during exam
ü  Draw the diagrams & charts neatly and practice as per exam oriented question
ü  Show the calculations and working notes clearly
ü  Read the questions carefully
ü  Do not panic while drawing tables, graph & diagram
ü Try to complete within time frame based on your experience during practice session


I think the above strategy is sufficient to attempt statistics part in a good way to score 100% marks and implementation part is necessary to score maximum marks in this exam. Please let me know the other irritating area for mains preparation so that I can target on that part to help civil service aspirants.

Comments, suggestions and queries are always invited.

Best of Luck!

Memory Problem: Here is the Solution!


As the syllabus is huge for civil service exam, most of the candidates feel problem of recalling the matter they have read. Every human being have more or less same memory then why some people are good at recalling things while some take time  to recall or mix up things while recalling?? Answer to this question is more time revision better your recalling power is. Let me clear this with an example, suppose you are new to a city and have to reach at particular address. In the first time, you will ask some people and then with great effort will reach to the desired address but next time when you will be travelling to the same city you will be better aware about the street, roads or some landmark. More number of times you travel the city the better will be your recalling power regarding that city.

Something similar happen with our brain as well. When we first read some new thing, it takes time to understand and to become familiar with that topic. The more number of times we are reading that thing the better will be your memory or recalling power. So few tips that will help you in improving your memory are:

ü  More number of revisions and timely revision of your subject will ensure better recalling ability.
ü  Understanding of concept help you in improving your memory as compared with the simply cramming the subject matter.
ü  Eat less than your hunger, it really works. It has a scientific reason; when we eat our food, our blood circulation moves from our brain to stomach to digest our food which makes us feel drowsy after having our lunch or dinner. So next time try to have half chapati less than your real hunger.
ü  Take sleep for atleast 7-8 hours in a day, it has again proved by scientific researches that good sleep helps in better recalling power.
ü  A good exercise regime or yoga is necessary to drain carbon di oxide out from your brain and to fill it with the fresh oxygen. Keep atleast one hour in daily regime for good exercise to give freshness to your mind.
ü  Give your mind some fun. Hobbies are important part of life and some time should be devoted in a week or daily for your hobbies like playing, listening music or chatting with your friends.

I hope the above tips will help you atleast to some extent. Last but not least, a happy person & positive mindset helps in making difficult things easier.

Current Affairs: Key for Success in Civil Services


Current affair is the most important area for Mains exam, although till 2010 it was an important area for prelims also but now in prelims it is conspicuous by its absence. One should thoroughly prepare this area for Mains exam as 80% of GS paper comes from directly or indirectly related to current affairs only. Any question in mains exam comes because that question was somewhere in news during that period.

A candidate should atleast cover current affairs for last 10 months before mains exam i.e. from January to September 15th should be covered for mains purpose. One should read the newspaper till 15-20 days before the exam e.g if this year mains exam is starting from 5th October so a candidate should at max read newspaper till 15th September to cover important news items. News from June to Sep 15th is most important for mains exam as most of the questions come from these three & half months, hence a candidate should read these months’ newspaper thoroughly with keeping in mind 2 marker, 5 marker in mind. One should not break the continuity while reading the newspaper and not even a single day newspaper should be left to keep one’s information updated.

How to cover a newspaper?

Most of the candidates are confused about number of newspapers to be read and how to read a newspaper. I will suggest a candidate to read only one newspaper carefully. I used to read only The Hindu and a student should not devote more than two hours on reading the newspaper.

One should not read each & everything in the newspaper. One should leave state news and political news directly and should focus on front news, editorials, National News, International News, Economy or business news & sports news. Self notes are necessary to cover the newspaper and without self notes a newspaper becomes useless as it is impossible to remember each & every news item and cuttings of newspaper unless organized is of no use to a candidate. One should prepare self notes like he/she is preparing his/her own magazine, thereby, dividing it into different sections like:

ü  Personality
ü  National News
ü  International Affairs
ü  Committees
ü  Awards
ü  Science & Tech
ü  Economy
ü  Ecology & Environment
ü  Sports etc

One should be careful while reading editorial as well as all editorials are not important from exam point of view. If some relevant information can be extracted it should be jotted down in your notes or if complete article is important, the same can be pasted in your current affairs notes as well. This process of notes making will make your revision part easier as all the reading material will be organized at one place.

While reading newspaper, 80% time should be devoted for reading the newspaper and 20% time should be spent to think over it and proper analysis of news item. One should try to frame some logical questions from the news item which an examiner can frame for mains exam. It will help in increasing the analytical ability of a candidate and will help in answer writing during mains exam as well.

How to read Magazine??

Magazines served as support function while preparing for current affairs; hence these are only supplementary to your newspaper reading. I will not suggest a candidate to read too many magazines rather focus on one or two magazine at maximum. One standard magazine like Chronicle or Wizard can be taken and second Yojna should be purchased to cover some important topics. Whenever magazine comes at the end of the month, a candidate should spent maximum 6-7 hours on a magazine and should select those areas which are not already covered in your notes and should be pasted or noted down in your own current affairs notes only, hence, it will complete your major news from the previous month.

Frontline can be used for covering only International Affairs as it covers international affairs meticulously, otherwise this is a very bulky magazine and can be left for other areas.

Integrated Study

What I meant by integrated study is that current affairs relating to traditional area should be integrated to concepts which you have learnt during prelims study e.g. news related to economics should be seen in context of syllabus of economics and concepts of economics should be integrated with the news appearing in the newspaper e.g. Vodafone case was in the news and a candidates should see the conceptual dimension of economics related with this case like what is capital gain tax, what do you meant by DTAA, what is round tripping etc. because questions in mains will not come directly and examiner will be more interested in application of concept by the student with the news analysis and impact of news with the administration of the country.

Other Sources of Current Affairs

Television can be a good source if you have access to it. Do not spend too much time on it rather devote half an hour on DD news for the news item for the whole day. DD news is compact and easy to understand and next day before reading newspaper one will also be aware about the world news for that particular day.

Internet can also be a good source of information but it should be used for limited purpose only as most people have tendency to spend more time on social networking sites or for chatting etc. So keep your internet surfing for important things only. Some good sites are available for civil service exam preparation like UPSCportal.com. ias100.in, civilserviceindia.com etc which covers day to day important current affairs news, these sites can be checked at the end of the day to cover your current affairs part.

Some important documents like Eco Survey, Census data, NCERT books etc are now available on internet and can be downloaded to save the purchasing cost if one is comfortable with online reading.

Some important topics one should cover from current affairs point of view area as follows:

Health Issues:

India is always put ahead of other countries because of “Demographic Dividend”, but it can be helpful only when a country have a proper health facilities system in place. Health related topics have also become very prominent in GS exam. One should cover this topic from India Year Book like health schemes, (In 2011, question from this section was on PC & PCNDT act, 1994 as female foeticide has reduced child sex ratio to 914 in 2011 from 927 as compared to 2001 census) major government health programs, recent epidemic outbreaks etc. A candidate should keep his mind open in the exam and even if he/ she are not aware about exact content of question, answer can be produced on the basis of commonsense. Some magazines also covered special issues on health areas which can be relied upon for mains exam.

New researches in health sector regarding drugs, some innovation should be given special attention.

Security related issues:

Internal and external security threats have become menace for any country in the present world. External security issues for India are Terrorism, Kashmir issue, Narcotic drugs smuggling, Pirates threats, Eastern boundary threats and Internal security issue includes Naxalism, communalism etc. These issues can be seen as latest development in the GS paper as well. In 2011, question was related to pirate threats and government recent efforts to tackle the piracy attacks. Magazines like chronicle or wizard publish special articles on security related issues which can be referred to cover this area. A candidate should be aware about related laws on security issues, any new government program to tackle these security threats, para military agencies and their role, north eastern specific problems, National Integration Council etc.

Good Governance & Human Rights issues:

Good governance & protection of human rights are the hallmark of any welfare society. These topics have also gained importance in civil exam. A candidate should be aware about HDI report and India’s position in this index. How to calculate this index and what improvements can be made to improve the index etc. Human right issues like right to life, right to water, right to health, right to fair trial etc should be read by a candidate. Magazine like Yojna gives special issues over human right & good governance issues which should be used for preparation. RTI, Citizen Charter & Lokpal related topics should be thoroughly covered, although these issues seem traditional but still these are favorite areas for the examiner.

Environment & Ecology related issues:

Environment value is now clearly evident in UPSC exam also. Those candidates appeared in this year prelims can very well understand the importance of this area for mains exam also. A candidate should be well prepared for environmental conventions like Ramsar Convention, CBD, UNFCCC conventions etc. The Ecological terms like coral reef, water eco system, bio diversity, IUCN red list etc should be on finger tips of a candidate. A candidate should be very well aware about various laws, heritage program etc. to get hold over this area. Believe me guys; environment has emerged as very important area in changing pattern of this exam. There are so many books available on this area in the market; a candidate should select carefully some good books to cover this area or special issue of magazine like chronicle on environment can be used to cover this area.

Apart from the above mentioned areas, a candidate should also read latest demographic data like Census data. Census data can appear in any exam and often proved to be very scoring during mains exam. A candidate should also pay attention to the traditional areas like government poverty schemes, employment scheme or any other scheme recently introduced by the govt. In 2011, question on renamed scheme of NRLM appeared in the exam.

One should behave like a SWAN while preparing for mains preparation which selects only useful item from the water and leave the rest of the thing in the water; similarly a candidate should read only important items for the exam point of view and leave the rest of things.

Best of Luck!

How History can make your future??


History in civil service exam has always been a scoring area for both Prelims & Mains, if prepared properly but most of the time it is neglected out of sheer negligence. It has been an easy area because history cannot be changed and good basic analysis of the subject can help in scoring marks. Good books are available on this area but too many references may create some confusion. In prelims, it is an area of problem also for many candidates because syllabus is huge and now a days questions are not even sure from both ancient & medieval history. However, still due to changing pattern of exam ancient & medieval history based questions are somehow managing to come in almost every prelims exam.

Some candidates choose to leave ancient and medieval history but it is not prudent on the part of candidates to ignore this area completely. Now prelims paper contains 100 questions and atleast 3-5 question comes from ancient history alone, precisely speaking 3-5% of questions come from this area. So a candidate should not ignore both ancient & medieval history completely and prepare for atleast some selected areas for it.

Prelims:

Ancient History

Ancient History covers time period from 10000 B.C. to 7th Century A.D. appx. It covers some very important areas like Indus Valley civilization, Pre Vedic & Vedic age, Jainism & Buddhism, Maurya period, Satvahnas, south india history & Gupta period etc. Questions mostly based on concept clarity from Ancient India are being asked in the exam like in 2011 pre exam question was “The Jain philosophy holds that the world is created and maintained by” supported by four options. Fact based questions were asked before CSAT exams on this area but now UPSC expects a candidate to have a conceptual clarity on this area rather than fact based knowledge.

What to read??

ü  Class XI book on Ancient History of India (Old NCERT book)

ü  Ancient History by Romila Thapar or Chronicle special issue on ancient history and also check out relevant current affairs from newspaper also. ( Friday supplement of The Hindu  is good for current affairs)

Medieval History

Medieval History for a long time is not contributing a major role in prelims question paper and hence reasonable risk can to taken to leave some area as well. Medieval History covers time period from 8th Century AD to 18th Century AD till Mughal period. Some important areas in medieval history with focus on art, architecture, bhakti, sufism, regional cultural development and personalities are:

ü  Cultural contribution of Islam alongwith kingship
ü  Delhi Sultanate
ü  Sufi & Bhakti movements of Kabir etc.
ü  Mughal period

The above is an illustrative list of topics and a candidate is required to read atleast some above stated important topics, however, due to paucity of time during preparation and a huge syllabus some area can be left also.

What to read??

ü  Class XI book on Medieval History of India (Old NCERT book)
ü  Chronicle special issue on medieval india history

›› Best way to study history is to study it chronologically; it will help you establish the link between important events as well; do not go for unnecessary factual details.

Modern India (Both for prelims & mains)

Modern history is the most important area to be tackled in the History paper both from the prelims as well as mains point of view. Typically, period for modern history is taken from 1857 AD to 1947 AD i.e. from Indian National Movement onwards, but i will suggest candidates to read this area from 1772 AD i.e. from first Governor General of Bengal (Lord Warren Hastings) for both prelims & mains. Questions in mains are even asked before 1857 war like subsidiary alliance, contribution of any particular governor general etc.

List of topics to be covered from this area:
ü  All Governor General
ü  Social, Religious & Tribal Movements ( Very important topic)
ü  The Revolt of 1857
ü  Indian National Congress & Concept of Nationalism
ü  Swadeshi Movement
ü  Surat Split
ü  Revolutionary Activities
ü  Important events from 1905 to 1947
ü  Non cooperation Movement
ü  Gandhian thought & his methods to fight against British Govt.
ü  Civil Disobedience movement
ü  Administrative Changes after 1857
ü  Economic Impact of British Rule in India
ü  Development of Indian Press
ü  Development of Education in India
ü  Civil, Police & Judiciary during British rule
ü  Peasant Movements, Working class movements & farmer movements
ü  National Movement: Towards freedom & partition ( 1939-1947) Very Important topic
ü  Important personalities associated with  freedom struggle & their contribution ( 2 Marker)

The above topic largely covers the syllabus for modern India and a candidate should create conceptual clarity on these topics alongwith factual knowledge as UPSC is now asking more concepts based question both in prelims & mains.

What to read??

ü  Class 6th to 10th NCERT books (old one) for basic clarity
ü  Class 12th NCERT book ( Old one) by Bipin Chandra
ü  Spectrum’s book on Modern History ( A must book to read)

Although there are lots of books available for history syllabus, but I will advice candidates to keep their material limited to few good books and rather should read same books again & again to get more clarity on this area. I find spectrum on Modern History very good and it largely covers the entire area for mains, though cross check for factual details can be made through other books or internet also. Internet can also be an additional source for History but be careful while reading it from Wikipedia as there can be areas where different authors have different opinion and hence authenticity for the same should be checked from other sources as well, however it is easier said than done, therefore patience is the key.
If a candidate has conceptual clarity on this area, i don’t think he/ she will find any difficulty in writing answers in the main exam. Sometime questions are asked indirectly also, but with careful reading of question, it can be answered easily. A candidate should keep his/her mind open and should use commonsense also to answer difficult questions. For sincere and committed students i am hereby making available email link of my Professor Vikas Bhardwaj for any queries and in depth Guidance: vikkyswy@gmail.com.Best wishes

Best wishes to all UPSC aspirants!
